Nah, I use GrapheneOS. Unfortunately you need to install the play store/services initially to services and "enabled privileged esim access" in the network access to install esim. After that though, you can purge all the Google crap and easily uninstall it all. Esim will remain in your phone, even if you were to factory reset and reflash to another OS. You just have install esim only once and it's actually stored on the hardware level.
Only to initially install it. After you install the esim, you can purge the Google stuff and it'll remain working perfectly. Esim is actually on your phone at the hardware level.
