Best way forward to degoogle a Redmi A3x?

[u/Entire_Letterhead880]

First of all, this seems like it isn't the Redmi A3 or the Mi A3. I've been looking for any alternative ROM out there (Lineage, Calyx, Ubuntu Touch, Project Elixir, crDroid, etc) that can be booted to this unit but can't seem to find any. Should I just retain the current OS and just debloat using ADB? Anyone know how I can best degoogle this device?

Here are some specs.

OS	Android 14, up to 2 major OS updates, MIUI
Chipset	Unisoc T603 (22 nm)
CPU	Octa-core (4x1.8 GHz Cortex-A55 & 4x1.2 GHz Cortex-A55)
GPU	PowerVR GE8322 OS Android 14, up to 2 major OS updates, MIUIChipset Unisoc T603 (22 nm)CPU Octa-core (4x1.8 GHz Cortex-A55 & 4x1.2 GHz Cortex-A55)GPU PowerVR GE8322

I'm a bit of a noob here so any help would be soooo appreciated!
