Skid Steering 1PWM for 2 motors in 1 esc?

Hello,
Since my stock ESC sucks I’ll buy a new ESC for my 540 brushed DC motors for skid steering.
However it looks like 1 channel(1 pwm only ) And as far as i understood, pixhawk needs 2 different pwm’s from the ESC to complete skid steering. Or is there a workaround?

I plan to switch to a 2s or 4s Lipo as this ESC supports lipo.
my rc boat: double horse 7006 (92cmx32cmx32cm)
stock battery: 12v nicd 1900mah 650grams
Flight controller: pixhawk 2.4.8
RC kit : 9x turnigy 9ch

Or should I buy 2 separate ESCs that supports up to 11.1V Li_po and change it to lipo?(12V nicd ones are way more expensive). I really can’t build a rudder. I know i’m too newbie for it.
Will arduboat(rover) on pixhawk work with 2 ESCs for skid steering?
