This will be an issue with the map you're loading. Correctly-implemented maps don't have this problem.

To actually try and answer your question, the only solution I've found is to try to click onto the map base and press + while it's highlighted until it's over the white. Unless you're playing genuinely competitive games, this'll basically be no issue with the slightly bigger map. Otherwise, there are competitive maps that are much more likely consistent. You also need to raise the height of the objectives to compensate, but it's at least functional without staring at white (or flickering, which is what me and a friend experience with some maps.)

But, I'd really like it if we got an actual answer on if we can actually do anything about the white base being removable for play via a script or not. There are some thematic maps that suffer from this problem, even if they're not the best for competitive play.

I'm back with a much better answer. Press f8 (this will bring your gizmo tool up, make sure it's currently on the far left "move" setting) click the map mat that's currently having a white/flickering problem and increase the y by increments of 0.01 until the white is no longer visible. Much more clean of a fix! Some terrain will literally just be a pixel or two into the ground, and that can be easily resolved if you're bothered by it by raising each of those pieces by the same amount you did for the mat.

Seems this Iteration of FTP Base is not entirely comaptible with "Battleforged-Workshop-Mod-Compilation", which is recommended on all channels known to me.

True, but this one worked for me:
