Unfortunately, if your source clip has more tracks than your timeline then Resolve doesn't currently offer any way to remove the automatic patch to those missing tracks... the result being that Resolve will add to your timeline however many extra tracks it needs (and receive the invisibly patched content).
Yes, it's a very flawed design, and yes, there have been many complaints about it, but addressing basic Edit page functionality has not been a priority for BMD for the last few years. Hopefully that will change at some point in the future, but until then the only patch control solution is to either a) ensure that your timeline has at least as many tracks as source - because if your timeline track count is equal to or greater than your source track count then you will be able to manage the source / target patching with the existing patch controls, or b) limit the number of active source tracks in your source clips (by using Clip Attributes, as Jim describes).
