The Red Devils also enjoyed a friendly win earlier this week; meanwhile, Azerbaijan shocked Sweden in Baku but are already out of contention.
Returning to action for the first time since an abandoned game against Sweden in October, Group F leaders Belgium hosted Serbia on Wednesday evening, as both teams built up to their final qualifier for Germany 2024.
Yannick Carrasco struck in the second minute for a much-changed home side, and the visitors ultimately could not provide a response, thereby extending the Belgians' unbeaten streak to nine matches in all competitions.
The Red Devils' penultimate qualifying fixture had previously been brought to an end at half time following the tragic shooting of two people in Brussels, where they were drawing 1-1 with Sweden, who have been left far behind in the race for a top-two place.
Although both nations were later awarded one point, Domenico Tedesco's team had already done enough to book their place in a third straight European Championship finals, having posted five wins and a draw from their first six games.
After recording a home victory in midweek, Belgium now host Azerbaijan to wrap up their qualifying campaign, having won 1-0 in last month's reverse fixture, when Carrasco was again the sole goalscorer.
Focus will then turn towards the upcoming Euros, and finally ending a trophy drought that even the lauded 'golden generation' could not conclude, despite several near misses.
While Belgium are bound for neighbouring Germany next summer, Azerbaijan will again be absent from the main stage, having started dismally in qualifying.
However, the latter stages of their Group F campaign have seen a welcome upturn in fortunes; most notably when the former Soviet state welcomed Sweden to Tofiq Bahramov Republican Stadium on Thursday, aiming to end a nine-game streak without a home win in European qualifiers.
Both nations had already been eliminated, with Austria joining Belgium in the top two, but Gianni De Biasi's men struck twice early on - through Emin Mahmudov and Renat Dadashov - and held on to their lead until being reduced to 10 men in the 57th minute.
Far from being deterred by such a setback, they kept their visitors out for another half-hour before Mahmudov finished things off late on, putting the gloss on a memorable 3-0 win over one of Europe's football establishment.
Azerbaijan had previously bounced back from defeat to Belgium by posting a 2-1 friendly victory over Jordan, then beating basement side Estonia for their first success in Group F. Then, after narrowly missing out on a point against Austria last month, the best was yet to come.
Having rested star striker Romelu Lukaku for Wednesday's friendly, Belgium boss Domenico Tedesco is expected to recall a man who leads the Red Devils' all-time scoring charts with 79 goals, including 23 from 33 matches in European Championship qualifying.
England-based trio Jeremy Doku, Leandro Trossard and Timothy Castagne could all be promoted from the bench, to feature in the hosts' favoured 4-3-3 formation; teenage defender Jorne Spileers will hope for some minutes after being handed his first senior call-up.
Gianni De Biasi - whose future will be decided in a meeting to be held shortly after Sunday's Group F finale - is likely to name a similar XI to that which started Azerbaijan's superb win over Sweden earlier this week.
Following their heroics on Thursday evening, Hatayspor striker Renat Dadashov and captain Emin Mahmudov will once again lead the Azeri attack.
Belgium possible starting lineup:
Sels; Castagne, Faes, Vertonghen, Theate; Tielemans, Mangala, Carrasco; Doku, Lukaku, Trossard
Azerbaijan possible starting lineup:
Mehemmedeliyev; Mammadov, Kryvotsiuk, Haghverdi, Cafarguliyev; Bayramov, Diniyev, Isayev, Sheydayev; Mahmudov; Dadashov
We say: Belgium 2-0 Azerbaijan
Competition for places - both in Belgium's Euro 2024 squad and their starting XI - should ensure the home side still aim to impress, despite already wrapping up qualification. Replicating an historic achievement just three days after seeing off Sweden will be too much to ask for Azerbaijan, who are set to suffer their fifth defeat from eight Group F games.
