Funky. Inside ~/.cache/ubports I found all the Volla Files inclund the scutterfile for the M6768 under mimameid/firmware. I started up spflashtool5 with root privileges and connected the phone with a USB Hub. Using mtk payload script I was able to send the payload to the phone and then set Option/Connection in Spflash to UART and a proper port. I was able to start flashing it with these files but I got
BROM Exception! ( ERROR : STATUS_TOO_LARGE (-1073479676)
Still, this is moving forward.
