LP5861: Analog Only Dimming?

Part Number: LP5861

Tool/software:

I'd like to use the LP5861 (or similar chip) in a noise sensitive application.  Is it possible to configure the LP5861 chip PWM settings so that the there is no switching on the outputs and use just the analog dimming options?  It's not clear from the datasheet if the PWM can be disabled or set to 100%.  Some other mixed dimming chips "100%" is actually = 99.9...% and there is still PWM switching noise generated on the LED lines.
