If these machines are managed by your company, in an MDM system... use that for it.
If these are unmanaged devices, using ClearPass Onboard is a good way to get them provisioned with a client certificate.
Besides that, the requirements are exactly the same as for Windows computers: clients should have a client certificate that is trusted by ClearPass, clients should have the root CA that issued the ClearPass RADIUS certificate installed and trusted for the authentication. Then configure the supplicant for that. How that is done really depends on the Linux distribution (like Fedora, SuSe, CentOS, Ubuntu, etc).

Hi Team,
We want to have cert based auth for the non-domain Linux machines with CPPM.
Kindly share the prerequisites and how to import the cert from the AD to the Linux machines.
