I tried to install kernel 5.x from backports in a frsh installed debian 10 and I failed because I have a 10G NIC:
echo deb http://deb.debian.org/debian buster-backports main contrib non-free > /etc/apt/sources.list.d/buster-backports.list
apt-get update
apt-get -t buster-backports upgrade
apt-get install -t buster-backports firmware-linux firmware-linux-nonfree linux-headers-5.4.0-0.bpo.2-amd64 linux-image-5.4.0-0.bpo.2-amd64
update-initramfs: Generating /boot/initrd.img-5.4.0-0.bpo.2-amd64
W: Possible missing firmware /lib/firmware/bnx2x/bnx2x-e2-7.13.11.0.fw for module bnx2x

W: Possible missing firmware /lib/firmware/bnx2x/bnx2x-e1-7.13.11.0.fw for module bnx2x
It doesn't find the firmware files. And the machine is not booting.

With the Debian stock kernel everything runs fine.
How can I install a kernel 5.x in debian10 from backports or another ppa (without compiling my own kernel)?
