Okay this is off topic a little but it needs more Attention. How do I unlock the last 2 variable driver variants on Beyblade Burst Battle Zero

Just use Variable. A lot. It takes an insane amount of battles, but after using Variable (and the second stage when unlocked) eventually you will get the first awoken variant, and then using that will eventually earn you the final stage.

Keep in mind that it counts as a brand new part, so you'll have to level it up again from scratch.
