When you say excluded, do you mean hidden or suppressed OR not there in BOM?
For hidden, create a display state.
For suppressed, create a configuration
No there in BOM: Sub assembly appears as single component in top level BOM unless you have promoted the child of sub assembly OR use the indented/flat type of BOM. In this cases, you can create a sub assy configuration with that part suppressed OR as Solid Air mentioned, move the row to top and hide.
You can hide an individual component of a sub-assembly in a upper level assembly without affecting the sub-assembly file. That only hides the component in the assembly where it was hidden. As you can see in the screenshot below, I hid a mailbox that's part of a sub-assembly. The sub-assembly is used twice in that assembly, and the other instance is unaffected. Of course the hidden component will still show up in a BOM, but you didn't mention BOMs so I don't know if that's a concern for you.
My suggestion is to create a separate configuration in the subassembly with the part excluded. Otherwise, move the part to the end of the BOM in your drawing and hide the row.
