Is cPanel's Let's Encrypt client affected by the TLS-ALPN-01 revocation happening on January 26th 2022?

Question

Let's Encrypt is revoking any SSL certificates issued before January 26th via TLS-ALPN-01 validation due to some irregularities in the validation method. Is the cPanel client affected by this? Will I lose my SSLs?
