Sure! There's a seam that can be gently split with razor/Xacto knife.

Trace from the black-wire terminal onto circuit board and you'll find driver-transistor. Get part# off it if not fried. Otherwise, should be same part# as one on green-wire side.

Desolder driver transistor and replace with new one.

That's how I'ved fixed many automotive ECUs. Mainly Bosch Motronic boxes from Porsches that get fried when people install low-impedance injectors without appropriate ballast resistors.
