so something like this?

local f=CreateFrame("Frame")
f:RegisterEvent("GROUP_ROSTER_UPDATE")
f:SetScript("OnEvent",function(self,event)
	if (event == "GROUP_ROSTER_UPDATE") then
		if InCombatLockdown() then
			f:RegisterEvent("PLAYER_REGEN_ENABLED")
		else
			SetCVar("showQuestTrackingTooltips", IsInRaid() and 0 or 1)
		end
	else
		SetCVar("showQuestTrackingTooltips", IsInRaid() and 0 or 1)
		f:UnregisterEvent("PLAYER_REGEN_ENABLED")
	end
end)
