IPS signature HTTP2.RST_STREAM.Rapid.Reset.DoS

[unknown1020]

good morning friends.
As you know, there is a zero-day vulnerability "HTTP2.RST_STREAM.Rapid.Reset.DoS"
Currently in my firewall I apply what is the IDS (end client request) previously we have already recommended that i should apply the IPS.

I want to block the reported signature but it does not appear in the list of IPS signatures, I have searched for it by CVE but it does not show me results either. Currently this equipment has the IPS version:

Search another firewall for the signature and if ican find it.

Is the issue the version of the IPS?
