U.S. constitutional text treats entrenchment as restricted to constitutional amendment.

Evidence

As a textual matter, the anti-entrenchment principle has been variously grounded in some combination of the Article I grant of limited legislative powers, the provisions of Article I specifying limited terms of office for congressional representatives, and Article V, which has been understood as creating an exclusive pathway for supra-statutory entrenchment. — Daryl Levinson and Benjamin I. Sachs, Political Entrenchment and Public Law, 131
