You have multiple choices.
Change to 5.8, or 5.4 whichever works for you.
If you are sticking with 5.6 for a reason, then you can remain on 5.6-rt for now.
To stay on 5.6-rt:
On boot, you should have an option to select other installed kernels (second option in the menu I believe), choose the RT kernel, and it should work.
If the system is stable in the long run, remove 5.6 with sudo mhwd-kernel -r linux56
To change:
Install 5.8 kernel sudo mhwd-kernel -i linux58
Try it out, if it works in the long run, remove 5.6 with sudo mhwd-kernel -r linux56
If it fails, boot back to 5.6, remove 5.8, install 5.4, try that out.
Make sure you always test out the new kernel before removing the working one you are changing from.
