Hi Anton,
That's great!
See my previous post for eg25-manager configuration, change the IMS config.
This what you need to change to disable VoLTE support even after reboot:
It works for my Pinephone so should for you as well.
Weird that 4G calls work if VoLTE is 0 as then calls should switch to 3G....no idea about the AT+CFUN though I understood it as being a reset...I might try with my Pinephone over the weekend. Note that by default eg25-manager has IMS set by MBN so enabled for you it seems.

Code:
# Enable VoLTE support
# { cmd = "QCFG", subcmd = "ims", expect = "1" },
{ cmd = "QCFG", subcmd = "ims", value = "2" },
