Kakute H7v2 with ELRS receivers

Hello! I want to ask, can i use ELRS receivers with Kakute H7v2? I know, that i need to build custom firmware and add RC_CRSF_PRT_CFG parameter. But i don’t have a receiver on my hands right now and I can’t test it. So I would like to know if it is possible to do this in theory with the latest alpha firmware (v1.15.0)?
