Rock 5C official CLI image contains desktop environment?

Hi, I just got a Rock 5C and a Penta Hat to build a NAS. Downloaded the official Debian CLI image from
https://github.com/radxa-build/rock-5c/releases/tag/rsdk-b1 and installed to an SD Card. However, when trying to install Open Media Vault from https://github.com/OpenMediaVault-Plugin-Developers/installScript, I got an error saying that “This system is running a desktop environment!”. Does this image contain a disabled desktop environment? Or there’s something wrong with the OMV install script? I searched the forum and saw other people were able to use OMV but none mentioned using the Rock 5C or this image specifically.

I dug a little and found that what seems to be triggering the error is the package “radxa-sddm-theme”. The script checks for installed environments with dpkg -l | grep -Eqw "gdm3|sddm|lxdm|xdm|lightdm|slim|wdm".
This package description on dpkg -l is “Radxa SDDM theme overrides”. Since I don’t run SDDM, I thought about removing this, but this creates a dependency issue with the packages: radxa-sddm-theme <- task-rockchip-xorg <- task-rockchip <- task-rk3588 (read “<-” as “is a dependency of”).

Running dpkg -l again shows the following descriptions for the packages:

task-rk3588       Metapackages for common RK3588 vendor packages
task-rockchip      Metapackages for common Rockchip vendor packages
task-rockchip-xorg   Metapackages for Rockchip X.Org.

The question now is: is it safe to remove these packages or can this break the system somehow?
