Disable Incoming Midi Clock on USB Only?

Hello! I want to have the incoming midi clock enabled for my TRS midi input. But disabled on my USB midi input. My setup is something like this (simplified)

MIdi Keyboard (master for clock) => Organelle M => OP1

The problem is, there is no way on the OP1 to stop sending a clock signal. Thus, I get a loopback issue.

Is this doable somehow?

Many thanks.
