Proxy CA expiring

Hi,

I receive the notification :

[WARN-600] Certificate(s) will expire

1 certificate(s) will expire within the next 30 days: Proxy CA

But we do not use the Web Protection and we don't have a licence for the Web Protection

"Licensing Info - This page is disabled as you either do not have a relevant subscription or the relevant subscription has expired!"

So it's impossible to click on regenerate.

I don't want to disable the mail notification to keep the alert for others certificates. Is there any way to delete/disable this certificate without a licence ?

Thanks.
