Messages relating to org.freedesktop.home1 and org.freedesktop.resolve1 can be ignored
But if you do not want messages spamming journal:
To get rid of messages for home1 edit file /etc/pam.d/system-auth
sudo nano /etc/pam.d/system-auth
and comment out the 4 lines relating to pam_systemd_home.so with #
/etc/pam.d/system-auth
#%PAM-1.0
auth required pam_faillock.so preauth
# Optionally use requisite above if you do not want to prompt for the password
# on locked accounts.

auth [default=die] pam_faillock.so authfail
auth optional pam_permit.so
auth required pam_env.so

# If you drop the above call to pam_faillock.so the lock will be done also

To get rid of messages for resolve1 Network manager can be configured to ignore systemd-resolved
sudo tee /etc/NetworkManager/conf.d/no-systemd-resolved.conf <<<'[main]
systemd-resolved=false'
