No need. It is already there - "The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people."
The Constitution says nothing about the Federal government owning or controlling land. Another amendment won't do any good with a regime that ignores The Constitution anyway.
Except the government ownership preceded the states
Actually Article 1 section 8 specifically enumerates the powers of Congress with regards to owning land.
