Got it. Sorry, I don’t see a simple solution for this with how things work currently.

You could use something else to generate the clock, send that to the H90, and set the H90 to THRU. Something like this would be a good choice: https://www.disasterareadesigns.com/shop/p/micro-clock

I can let you know if we add MIDI filtering options to a future update. Sorry for the inconvenience.
