Trying to disable server's footstep sounds using resource pack

I've been trying for a little bit to make a resource pack to disable footsteps sounds for compatibility with the mod Presence Footsteps.

However, despite the pack working as intended in Singleplayer, when I join the server, there are seemingly custom footsteps added by the server.

The only sound working as intended on the server is wood (block.wood.step) from my testing, and disabling the Players volume slider also does not silence it. Anyone know what other sound keys to disable on my sounds.json file, or if there's any other fix I can do?

Also really sorry if this is not the right place for this kind of question. Just looking for help with this
