Block accessing to SSL Inspection exempted host

I want to prevent users from uploading files using zoom’s chat feature.
(I know that zoom is able to configured to prevent uploading files, But I want to prevent uploading not only our company tenant, but also other tenants like free account associated tenant.)

So I configured SSL Inspection enabled and made some File Type Control policy.
But I’ve found that when “Block Undecryptable Traffic” enabled, SSL Inspection prevents user invitaions on zoom.

Is there any way to balance below two function ?

  • Traffic of zoom should be exempted from SSL Inspection.
  • But, traffic to specific host( that serves file uploading function shoud be Blocked.
