Kvyat, the Toro Rosso refugee, tested a European Nascar during the "recruitment tests" at Italy's Franciacorta circuit.
Galpin told France's Auto Hebdo: "He enjoyed driving the car without these extra systems that are in Formula 1.
"But they were tests purely for pleasure. Daniil is still focused on a career in Formula one, and his plans do not include moving to a Nascar series."
Kvyat is currently without an F1 team, having been dropped by Toro Rosso.
