I don't think there is an easy way to do either, and it's mostly a joke, but the line is a reference to this proposal from Floppy Disk Guy
"Regular" full nodes generally don't signal support for a soft fork, with two exceptions: the proposal I just linked to is one exception and the other is bip148, which was controversial and hasn't been used ever since segwit
Mining nodes signal support for a soft fork either via bip8 or bip9
Ah, yes. I thought it was just a mining node thing only, but I didn't know for sure and started questioning myself when I read that line in your song.
