So @rpuga is correct in the fact that you can’t specifically create an exclusion and give it the scope of “Everything in this vulnerability category” but you can create asset groups based off of that installed software or specific vulnerabilities and then create an exception for the specific vulnerability scoped to the full asset group.
So each specific vulnerability will need to be excluded one at a time but scoped to the full asset group.
So for example if you had 10 specific vulnerabilities but they were present on 100 servers. You could create an asset group based off of those 10 vulnerabilities to include those 100 servers. After that is created you would only need to do 10 exceptions but scoped to that asset group.
The more specific vulnerabilities there are, the more work there will be in creating the exceptions for sure though.
