You should be able to get what you need with the channel four band parametric eq.
If you need more eq you could assign that channel to a group, group outs have both the parametric and graphic eq’s on the output.
Remember if you assign a channel to a group you need to unassign that channel from the main LR mix if mix if the group is sending to main LR mix.
All said maybe the main system’s set up needs looked at some.
