Fry the EFI chip of a 2016 MacBook Pro

So, this is a unusual post... I have fried my MacBook Pro 2014 EFI chip by accidentally booting with Clover a couple of years back, and I was lucky enough that it was still under warranty so Apple would replace the motherboard (it was ChimeLooping)

​

I'm experiencing issues with graphics on my 2016 MacBook Pro w/TouchBar that is only occurring in games but since the Geniuses cannot actually witness it in store, they don't want to change the logic board.

So I'm looking for a simple way to fry the motherboard like it happened with my 2014 MBP, but I booted many many times with an old version of Clover on it, but it keeps on working.

Would you guys have an idea on how to proceed?

thanks :-)
