tuned 2.20.0, CentOS 9. On one server restarting service is OK:

systemctl restart tuned

Mar 26 21:01:26 server01 systemd[1]: Stopping Dynamic System Tuning Daemon...
Mar 26 21:01:26 server01 systemd[1]: tuned.service: Deactivated successfully.

Mar 26 21:01:26 server01 systemd[1]: Starting Dynamic System Tuning Daemon...
Mar 26 21:01:26 server01 systemd[1]: Started Dynamic System Tuning Daemon.

On another:

systemctl restart tuned

After this on 2nd server ipv6 is lost:

ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

       valid_lft forever preferred_lft forever

It reappears after systemctl restart NetworkManager:
