Cannot encrypt Realme 7 Pro running Android 13 (Project Elixir ROM)

I have Realme 7 Pro device with an unlocked bootloader and installed custom ROM: - Project Elixir 3.8 - Android 13 - Kernel 4.14.212 - Selinux Status "Enforcing" - Custom Recovery "OrangeFox R11.1" The phone is showing "phone not encrypted": I tried to follow this XDA thread to make the phone encrypted with no luck. When I use the stock firmware I got it encrypted normally with "FBE Encryption", but with custom ROMs, it's not. **Is it possible to encrypt the phone when using custom ROM? and how?** Thank you.
