This Red Hat documentation explains how the naming works:

You don't need to set kernel parameters to set the interface name.

Might look into 70-persistent-net.rules in addition to the article below (do
your web research for that and CentOS 7), it's a file you probably have to
create (not necessarily auto-generated as some documentation says) under
/etc/udev/rules.d.  There have been two known formats for that file and a given
format doesn't work in all cases.  Here are the formats I've seen, hope
it helps (everything below is literal except what's contained in the
less/greater than delimiters):

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="<colon-separated mac address, lower-case>",
ATTR{dev_id}=="0x0", ATTR{type}=="1",
KERNEL=="eth*", NAME="<new name>"

SUBSYSTEM=="net", ACTION=="add", DRIVERS=="?*",
ATTR{address}=="<colon-separated mac address, lower-case>",
ATTR{dev_id}=="0x0", ATTR{type}=="1", NAME="<new
name>"

Note the missing KERNEL==... in the latter form.

Hallo,

https://unix.stackexchange.com/questions/396382/how-can-i-show-the-old-eth0-names-and-also-rename-network-interfaces-in-debian-9

but it is important to use grub2 nad not grub.
