NIST FIPS 186-5 (Draft) has Ed25519. https://csrc.nist.gov/publications/detail/fips/186/5/draft https://csrc.nist.gov/publications/detail/fips/186/5/draft NIST SP 800-186 (Draft) has the curve definitions. But says only for Ed25519, not for X25519. They have a Weierstrass curve W-25519 that is isomorphic to Curve25519 that might allow using X25519 code, but that's way above my ability to judge. 'tptacek or 'jedisct1 or others will know. https://csrc.nist.gov/publications/detail/sp/800-186/draft https://csrc.nist.gov/publications/detail/sp/800-186/draft
