Since I haven't bred snakes for years, that was the only reason that I brumated some of my snakes (for fertility, they need a cool-down for best results).
So no, I feed my snakes all winter, and only 2 of them get fussy & self-impose a diet: my rosy boa, & my Texas longnose snakes. I offer as long as they accept, then quit.
Otherwise, my corn & rat snakes & spotted python could care less that it's winter. My ambient house temperature is set to 70*, & they all have UTH & over-head tank
warmth as needed, & they're all good with that.
