I have an IBM BladeCenter E with Debian 11 install on a blade server, and I am trying to set up the network with two interfaces (provided on each blade server): one for local network for NFS and one for occasional internet access with static address. NFS works and sometimes the static address did, too... Until I installed LXDE and all the stuff which comes along with it.
In the beginning, I just installed what comes with the Debian 11 netinst distribution on a USB stick because I couldn't set up the network at the time of installation. Then I somehow was able to statically configure the network via /etc/network/interfaces and installed NFS client side and LXDE and some other stuff like GCC and vim, and numpy.
But after I rebooted it to see if the NFS works (which it did), I couldn't connect to the Internet anymore. It keeps now adding dynamic addresses to all interfaces sans lo, in the range 169.254.x.x, which, as I now have learned, means it fails to connect to a DHCP server (because there is no any). There is no NetworkManager or netplan installed, and systemd-networkd is disabled. I tried adding systems configuration as well (as described here: https://forums.debian.net/viewtopic.php?f=5&t=142839&sid=ca6b09a442b04ebec06fbcb6c64f0f9e) but this did not help.
Can anyone please point me towards the possible solutions to this problem? Thanks in advance!

I also tried adding the systemd-networkd configuration as described in the link above, with the same information as in /etc/network/interfaces (/etc/systemd/networkd.conf has all lines commented out) but this did not help.
Also, I tried removing some DHCP-related software:
apt remove dhcpcd5 isc-dhcp-client isc-dhcp-common
Of which dhcpcd5 was not installed anyway but this did it help either.
