ExemptDomainFileTypePairsFromFileTypeDownloadWarnings

Disable warnings based on file extension for specific file types on domains. This policy is based on the Chrome policy of the same name.

Caution

The documentation for the policy for both Edge and Chrome may be inconsistent. The domains value must be a domain, not a URL pattern. Additionally, Firefox does not support using a wildcard (*) to mean all domains.

Compatibility: Firefox 102
CCK2 Equivalent: N/A
Preferences Affected: N/A

If you are using custom ADMX and ADML administrative templates in Intune, you can use this OMA-URI instead to workaround the limit on the length of strings. Put all of your JSON on one line.
