TPS650333-Q1: Not using one of the step-down converters

Tool/software:

Hi,

I'm using the TPS65033303RGERQ1 to power my board and a C2000 series microcontroller. I don't need the Buck2 channel. Is it safe to ground the PVIN_B2 pin and leave the LX_B2 and FB_B2 pins floating?

Will this have any adverse effects on the other channels or the stability of the system?

Thanks!
