PWM Pins on J20 about archimaddons HOT 1 OPEN

This still appears to be an issue with Archim on Marlin 2.0.7.2.
WIth:
#define SPINDLE_LASER_ENA_PIN 70 // digital pin J20 connector pin22 (PA17 aka digital pin 70)
#define SPINDLE_LASER_PWM_PIN 53 // digital pin - MUST BE HARDWARE PWM J20 connector pin17 (PB14 PWMH2 aka digial pin 53)

It's not seeing Pin 53 (aka PB14) as a valid PWM pin...

Ticket is over a year old, can we bump up the priority?
