I just experienced this with Set-AzFirewallPolicyRuleCollectionGroup
The docs say it's supported https://learn.microsoft.com/en-us/powershell/module/az.network/set-azfirewallpolicyrulecollectiongroup?view=azps-13.4.0

@JCFTW I'm from the Firewall team and checked our powershell code and I can see that we did not implement the support for -WhatIf. I added an internal item to track this status so we can approach it. This issue has been linked internally

Thanks for confirming. A quick win would be to throw an error for now if WhatIf is called until it can be properly implemented if it would take time to implement fully. Yes I did screw over my firewall rules whilst I was testing.
