Does The Apple have only one standart for russian keyboard? Or a few one?

I currently live in Slovakia but I speak russian and I'd like to order a MacBook Air M1 from autorised resseler "iStore.sk" of course with a russian keyboard but their employees do not know how the russian keyboard looks like and can't tell me will it be like double-languaged (like English + Russian) or with only russian. Definetly I need a double-languaged one, just like the Apple standarts but I'm not sure do The Apple has the keyboard with only russian letters on it or it's impossible. I find a site with Apple Standarts Keyboard (https://support.apple.com/en-us/HT201794) and I'd like to know if I order a MacBook with the russian keyboard will it be like this (like with double-letters)? Thank you very much!
