Impressive, well done. Undervolting would void the warranty prob like with oc.

Yes I will add this to the topic as this definitely voids the warranty on the mining boards

On the other hand, this will improve efficiency and heat problems, so on average this will improve the lifetime of the miner

Is it possible to detect modded firmware or clock changes if the device is hard reset?

As far as I know, no - you won't be able to see that. You could at any point flash the Bitmain FW onto the controller again.
But I'm not 100% sure about settings. So in this case I'd recommend to wipe all settings and flash back original FW; then there should be no easy way to see that you used a different firmware before.
