Enabled FileVault with disabled SSV possible with Big Sur? My Hardware is a 2019 MacBook Pro 15&quot; has the T2 chip and runs macOS 11.0.1.
After disabling SSV via csrutil authenticated-root disable and rebooting I can not enable FileVault. Unfortunately the error is very generic: &quot;FileVault Failed An internal error has occurred.&quot;
Is it possible to have signed system volume (SSV) disabled but FileVault enabled?
According to user experiences - this is not possible.
Disabling SSV will leave the system stripped out of  both SIP and File Vault.
