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.

My latest single is CTV - a song that tells why I want this soft fork

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](https://groups.google.com/g/bitcoindev/c/-NbdxKkaMQU/m/1FAF8EGSAQAJ) 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](http://bips.xyz/148), which was controversial and hasn't been used ever since segwit

Mining nodes signal support for a soft fork either via [bip8](http://bips.xyz/8) or [bip9](http://bips.xyz/9)
