Hi there,

I would suggest you to create an Inbound rule in the defender so that you can add the RSAT as a trusted certificate.

To allow inbound network traffic on only a specified TCP or UDP port number, use the Windows Defender Firewall with Advanced Security node in the Group Policy Management MMC snap-in to create firewall rules. This type of rule allows any program that listens on a specified TCP or UDP port to receive network traffic sent to that port.

To complete these procedures, you must be a member of the Domain Administrators group, or otherwise be delegated permissions to modify the GPOs.
