No internet on installation media [r8169/r8125]

I'm installing arch on a pc with a MSI z490-a pro motherboard. I have no internet connection despite being connected to an ethernet cable. I know I'm supposed to install the right driver https://aur.archlinux.org/packages/r8125/ but I can't figure out how to install it within the installation media. I downloaded the source from the package and mounted it on a USB stick, but idk what to do from there.
How do I proceed with the installation?

I posted something very similar two days ago as "tg3 not active on installation media". There is a deafening silence.
lspci -k will tell you the driver required and modprobe <module_name> will tell you the state of the driver. But it must be listed as "in use" by lspci and mine is not on the Archlinux install.

Easiest solution would be use Tethering for the installation including base-devel then you can build the package on the new installation.
More complicated is build the package on another Arch installation.  Ensure the kernel version of the build machine matches the kerne version of the installation media.
Most complicated copy onto the USB stick from the ALA from the data of the ISO the following packages:

autoconf
automake
binutils
bison
diffutils
elfutils
fakeroot
flex
gc
gcc
groff
guile
libmicrohttpd
libmpc
libtool
m4
make
patch
pkgconf
texinfo
which

As well as linux-headers needed by r8125.

Thanks loqs, tethering worked out of the box although I'm puzzled why dhcpcd is starting but not find an interface when there is clearly a working interface to be found.
