Assuming you are using V9 Resolve, you can go into the Resolve Preferences window, select the Advanced area, and add this line to disable the Red Rocket card:
Red.Rocket.Enable = 0
Save the preferences, and restart Resolve.
After you restart Resolve, you can check in Resolve Preferences / System Overview to verify the Red Rocket is not being used.
To re-enable the Red Rocket card, either remove the line above from the Preferences Advanced area, save Preferences and restart Resolve, or add a # at the front of the line above, and save Preferences and restart Resolve.
