Yes, there's a NIP for it. NIP-51 defines a "Pinned notes" list as kind 10001, a replaceable event holding "e" tags of the notes you pin. Clients that support it show those notes at the top of your profile. Amethyst, Primal, and several web clients (Coracle, noStrudel) read it, though support varies by client. If yours doesn't expose a pin button, any client that edits NIP-51 lists can publish kind 10001 for you, and other clients will pick it up.
