I withdraw my suggestion.
If you have a an x88-64 AMD-Intel, not ARM and it's supported by
MrChromebox and
Chrultrabook Docs then better to install Native Linux Mint 22.1 and Mate Desktop. Then everything works better and faster. Installing as good or better Android in a container on Linux can have Playstore and ARM emulation via Anbox.
ChromeOS Android on x86-64 is poor and Crostini Liinux is crippled and in a container. Stupidly not viable to use the real Linux that ChromeOS runs on. ChromeOS is using Chrome browser to do the windows/desktop.
You don't need to initially disable Write Protect (WP) to install a dual boot native Linux (ctrl L at developer screen after doing scripts in Developer mode), and you can wipe ChromeOS entirely after using the ChromeBrowser Extension to back it up. Then if that works you can disable WP and install alternate BIOS to only have Linux boot.
Faster boot. Crostini is slow to start and also sometimes the network service doesn't start. ChromeOS is much better than a few years ago, but still pointless if you don't want Google Docs, Sheets & Canvas with Gmail and Chrome Browser. Android and Linux support is still poor.
I don't need suspend now, which on Intel will run battery flat as shutdown is near instant and boot to desktop inc log-in about 20 seconds. Longer battery life (8 vs 6 hours using Linux).
ChromeOS is controlled and updated at whim of Google. In T&C. The ChromeOS updates don't update Crostini Linux. The backup system for ChromeOS, Android and Crostini Linux is rubbish.
