You can install Homebrew (a package manager for macOS and Linux) without disabling the read-only partition with sudo steamos-readonly disable.
The package manager can be used alongside Flatpaks. Some software is only available on Flathub, and some software is only available on Homebrew.

1. Switch to desktop mode (hold power button until a menu appears, then select "Switch to desktop mode")
2. Click the logo at the bottom left, go to System, then go to Konsole
3. Set a password (needed for sudo access):

   passwd

4. Install Homebrew using the steps here: https://brew.sh/
   Don't install any additional libraries from pacman or brew yet. Also, do not append to .bash_profile yet, otherwise it will break Steam.
5. Add to .bash_profile with a check to make sure it is running in Konsole:

   echo 'if [ $(basename $(printf "%s" "$(ps -p $(ps -p $$ -o ppid=) -o cmd=)" | cut --delimiter " " --fields 1)) = konsole ] ; then '$'\n''eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"'$'\n''fi'$'\n' >> ~/.bash_profile

6. In Konsole's menu bar, go to Settings -> Manage Profile
7. Press "New"
8. Check "Default Profile"
9. Set "Command" to /bin/bash -l (that is a lowercase l, not a number 1)
10. Click OK twice
11. Add brew environment to current context:

    eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv)"

12. Install glibc (the important thing is headers). This is needed in order to compile software.

    brew install glibc

13. Install GCC:

    brew install gcc
