I looked for what I have

$ apt list --installed | grep -i smb

WARNING: apt does not have a stable CLI interface. Use with caution in scripts.

libsmbclient/focal-updates,now 2:4.13.17~dfsg-0ubuntu0.21.04.2 amd64 [installed]
libsmbios-c2/focal,now 2.4.3-1 amd64 [installed,automatic]
php8.0-smbclient/now 1.0.6-6+ubuntu18.04.1+deb.sury.org+10 amd64 [installed,local]
smbclient/focal-updates,now 2:4.13.17~dfsg-0ubuntu0.21.04.2 amd64 [installed]

and removed some

$ sudo apt-get remove smbclient/focal-updates
$ sudo apt-get remove php8.0-smbclient
$ sudo apt-get remove libsmbclient/focal-updates
$ sudo apt autoremove

so I only left with this

libsmbios-c2/focal,now 2.4.3-1 amd64 [installed,automatic]

The warnings have gone now
