Hi,
Have you tried disabling RADIUS as authentication Setttings first:
Download JSON, modify, upload modified JSON.
It's a little bit of a pain, but I was able to do it by downloading the json file. Look for the following:
"com.vmware.horizon.adapters.certificateAdapter.CertificateAuthAdapter", "enabled": "true", "enableCertCRL": "false",
Change enabled to false, save to a different name and upload the file. Worked for me.
After that you should be able to disable RADUS from Edge Services.
