Is it possible to have OpenMediaVault+Plex+Home Assistant under the same machine (raspberry pi 4)

Hey guys, I just got my Raspberry Pi 4B 4GB setup with OpenMediaVault and Plex (running inside a docker stack) yesterday, and I’m wondering if I still have the headroom to add in Home Assistant on the device. The reason I want to add Home Assistant is to allow use a plugin to allow Plex to communicate with my Google home.
