The knobs on your oven are overwhelmingly likely to be either completely made of plastic or contain a large percentage of plastic already. Typically they’re made of ABS or PBT.
PLA probably isn’t a good choice for this application but you could absolutely print some knobs in ABS or ASA and you’d be fine. You can even get PBT filament, but that’s probably more hassle than it’s worth and ABS is cheaper.
