RFC 9155 [1] deprecates the use of SHA-1 in TLS & DTLS 1.2 digital signatures. This does not affect SHA-1 in TLS server certificates which has already been disabled.

Other TLS implementations have started deprecating their usage. Chrome 117 has removed support for signature algorithms using SHA-1 for server signatures during the TLS handshake [2]. OpenSSL changed their default security level to 2 in version 3.2.0, and this level disables SHA-1 TLS signatures.
