2 CUL Sticks same time 433 / 868 Mhz supported?

Hello everyone, I would like to control with my Raspberry Pi and Openhabian 433 Mhz modules as well as 868 modules from Homematic. Now I have come across a tutorial how I build these two CUL sticks myself.

Now my question, are these then also Openhab compatible? Does anyone have experience with it?

Currently I use an 868 Mhz module from ELV, the problem is that all GPIO pins are occupied and I need an alternative. Here is the module I currently use: https://www.elv.de/homematic-funkmodul-fuer-raspberry-pi-bausatz.html

thank you in advance
