How can I disable support on this specific part of the model?
Hello, this is my first post so sorry if i made a mistake in this post.
I can't remove supports on the part of the model i have made, the model has its issues and is not great but I'm more focused on removing support on this specific part of the model.
I have tried Paint-on supports with or without clipping of view and i could not reach the part where i need to remove support.
I have also tried adding negative volume cylinder in the middle that did not give me expected results.
I don't need supports there because there is a cylindrical part that i want to insert during printing process.
Here is the part where i don't want support, and at the bottom i provided the file.

The file we need is your Prusa Slicer Project file. So slice it and then use File>Export Project to save the .3mf file. That will contain all your settings as well as the model and we can see exactly what you are working with.
Also your model is broken it has 268 open edges even after PS auto repair (they can be seen as purple edges in PS if you have Show Non Manifold edges enabled in your PS preferences. Also PS complains that it appears the model is defined in metres when loaded. You really should sort model issues out before slicing.
Looking at the file there absolutely needs support there otherwise you will be printing in mid air, there is this section 
Not attached to anything. However this is in the area where the open edges are. I suspect that is why its trying to support the area.
I've attached a zip file with a fixed version of the model as well as an example project, where I've repaired the non manifold edges as well as redone that area to print a single layer over that hole. This will allow the printer to bridge that area, requiring no support. As the layer is 0.24mm thick it prints as single layer so you can easily poke it out once printed if you want to.
I've used support painting to define the areas requiring support and set it to Enforcers only. As you didn't attach an original project I have no idea what printer or filament you are using so the example project uses a prusa mk3 and generic pla. You can compare the settings in one as well as the painted areas etc to your setup and go from there.
If you have any questions about it then please ask.
