you can use (in trixie) the ethX schema with a kernel command-line
parameter, in debian under /etc/default/grub:
--snip--
GRUB_CMDLINE_LINUX="net.ifnames=0"
--snap--

lead to:
--snip--
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc fq_codel
state UP group default qlen 1000
    link/ether 00:XX:XX:XX:XX:XX brd ff:ff:ff:ff:ff:ff
    altname enp0s18
    altname ens18
    altname enx005056b3d957
--snap--

Cheers, Volker
