That doesn't make sense, how are you going to connect from the "jump
host" to an end machine using a unix socket?

(If ssh forwarding is disabled but you are still able to make outgoing
connections, you can use some "ssh jumphost nc" variant in ProxyCommand
instead, like we used to do before ProxyJump).
