So by default V is Ping, but I want Nimble mod (to turn on front view) to be V,
so I changed Nimble to V key and Ping key to be X,
yet the ping menu still pops up with V and pressing X does not turn on the Ping menu.
tl:dr ping keybinding is broken

Tested out the new release "Ping-fabric-1.20.4-1.11.2", seems fixed, thanks

What version of Minecraft and Ping are you on?

Ping-fabric-1.20.4-1.11.1 , so Fabric and on 1.20.4
