Does anybody have an EFI for idea-pad slim 3 15IMLo5 or thinkpad T470s?

I’ve made EFIs before and I never had an issue, that was a couple years ago and I’m not sure if I’ve gotten rusty or I’m totally missing something but if anyone has an EFI for the ideapad 3 comet lake i3 10100, if not I’ll probably just try out my thinkpad T470s I don’t really need an EFI for that though
