This policy enables a list of TLS certificates that should be trusted by Microsoft Edge for server authentication, with constraints added outside the certificate. If no constraint of a certain type is present, then any name of that type is allowed. Certificates should be base64-encoded. At least one constraint must be specified for each certificate. The permitted_dns_names field is a list of DNS names that are allowed for the certificate. If the DNS name in the certificate request doesn't match one of the specified DNS names, the certificate isn't trusted. The permitted_cidrs field is a list of CIDR (Classless Inter-Domain Routing) ranges that will be allowed for the certificate. If the IP address in the certificate request doesn't fall within one of the permitted CIDR ranges, the certificate isn't trusted. Example value: [ { "certificate": "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", "constraints": { "permitted_dns_names": [ "example.org" ], "permitted_cidrs": [ "10.1.1.0/24" ] } } ]

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
