Help needed: 4.2.7 board, Marlin 2 and BL Touch

[CRAK]

I have swapped the 1.1.5 board in my Ender 5 Pro for the 4.2.7 board (preconfigured for Ender 3 Pro).
Since I'm using a Hemera Direct Drive kit (and a BL Touch) I need to apply a few changes to any standard (Creality / Marlin) firmware release.
I have cloned the 2.0.x branch (2.0.9.1) from https://github.com/MarlinFirmware/Marlin and added the configuration from https://github.com/MarlinFirmware/Configurations/tree/import-2.0.x/config/examples/Creality/Ender-5 Pro/CrealityV427

After applying the necessary changed, I compiled the script, had the printer to process the bin file noticed that is is actually showing "Ender 5 Pro" (instead of 3 Pro).

When the printer boots the BL Touch probe deploys and stows a few times while the bootscreens show. Once the home screen shows, the probe fails to deploy: not via the BL Touch menu; not in Auto Home.
The BL Touch is connected via the "Pinboard A" and the "Z-stop switch".

I have seen similar issues in earlier versions of Marlin (2.0.5.x) and even found a possible code fix in Conditionals_LCD.h (https://github.com/bigtreetech/BIGTREETECH-SKR-mini-E3/issues/221), but this no longer applies to the 2.0.9.x version.

Does anyone know how to solve this issue?
