Others have already laughed at this idea, but on a similar topic:

I know we’ve basically disabled a lot of features that sped up the CPU but introduced security flaws. Is there a way to turn those features back on for an airgapped computer intentionally?

The kernel option is mitigations=off, if you want to try adding it to your Grub command line? From the testing I've done, provides no benefits whatsoever - no more frames in games, compilation runs no quicker, battery life on a laptop is no better.
