There is no native integration. You would need to use a third-party "Radius as a Service" provider with Entra ID support.
HOWEVER, given your use case - I would instead move towards zero trust - and don't trust the local network. Only use it to provide Internet access. No 802.1x required.
With Business Premium you could/should use device compliance and use conditional access policy to enforce only authorised devices are allowed to access your systems.
I appreciate tihs is quite diffificult if you don't have a mature cyber policy. It often takes companies many years to get mature enough with their cyber deployments to get to this stage.
Another way of achieving this is to use Cisco Secure Connect Plus with the "Complete" package.

This DOES integrate with Entra ID, and assumes the local network is untrusted (zero trust). It will provide users with the same access to resources weather they are in the office or at home). You can also use conditional access policies to restrict access to the Umbrella SIG IP address ranges so no one can access your enviroment unless they have come thorugh this system.
And it does integrate with Meraki.
