Crosscall Trekker X4

Hello, I have a crosscall Trekker X4, a french smartphone, waterproof and really strong. I would like to install /e/ but I don’t know if it’s possible. Someone to help me ?
Android 8.1.0

Hello @lankalex, the WWW search engines don’t give positive information about alternative operating systems: no TWRP Recovery, no customROM; no LineageOS, no /e/ OS ROM; maybe the bootloader is locked.
