Is it possible to effectively ramp the PWM duty cycle to reduce inrush current?

I have some DC motors which I need to power and the power supply can handle the motors (I have a beefy 12V 60A output buck converter which is advertised as having "Short Circuit Protection") also, the supply can handle the motors during normal operations.But I'm a little unsure about the inrush current when first starting up.

I was wondering if I can use a current limiting circuit to essentially make this supply "Continuous Current Limited" so the supply wouldn't just trip its short circuit protection if the draw was too high.

The motors will be driven with a driver which can use PWM, is it possible to effectively ramp the PWM duty cycle to reduce inrush current?
