Yes, you can. Residentiall roof trusses are designed to bear only on the exterior walls at each end of the span.
Do truss roofs have load-bearing walls?

Can you replace trusses without removing roof?
You can replace old, worn rafters without removing the roof. Most roofs have either a system of rafters and joists or of trusses.
How do I know if a truss is load-bearing?
If you only have access to the wall framing and not the ceiling/attic space to see the joist/truss direction, then tightly spaced or deeper wall studs could be a sign that it is load-bearing since a heavily loaded wall would require more studs and a larger stud area to resist the applied loads.
Do houses with trusses have interior load-bearing walls?
Identifying load-bearing walls in the attic In modern homes, trusses generally bring the roof load to the exterior walls, making all interior walls partition walls (but not always). Older homes and some newer homes don't have trusses; they have framed-in-place roof rafters.
