Can't you use DDR3 in DDR5 compatible board?

No, the different generations have fundamentally incompatible interfaces, not just mechanically, but in terms of voltage and signaling.
Unfortunately not, each version of RAM uses a different physical slot.
Well, they're entirely different, not just slot. Intel 12th/13th/14th gens all support DDR4 or DDR5. However, the motherboards you buy can only support one or the other. I don't think there are a single AMD CPU that supports both?
