Upgrading from 15 to FreePBX 16 on Raspberry Pi

I’ve now got a working OS from the links given above, but I’m getting this message of “FreePBX 17 installation can only be made on a 64-bit (amd64) system!” when running the FreePBX installation script. I’m aware that my Raspberry Pi isn’t an AMD64, but I think it’s the ARM64 version.

Is there a workaround for this please?.
