The England international, currently on 28 top-flight goals this term, won the award in 2015-16 and 2016-17.
Despite the furore on social media when Spurs successfully appealed for Kane to be awarded the second goal in a 2-1 win over Stoke City in March, the 24-year-old insisted that the Golden Boot is not his main objective.
"It's been another good year, another consistent year and hopefully I can score a few more and try to get to that 30-goal mark in the Premier League," Kane told Sky Sports News ahead of the meeting with Leicester City.
"I'm happy, it's been a good season, it's been consistent over the whole season. There's been rare spells where I've not scored, I always try to improve and where I can get better and I've done better than last year.
"Of course, I want to retain the boot but consistency is the most important thing for me, getting 25-plus goals in the Premier League season after season. And there'll always be players who come and do well. Mo's had a fantastic year, who knows what'll happen, but for me it's about doing it year after year."
Kane has made 212 appearances for Spurs, scoring 138 goals and registering 22 assists.
