How to enable Schmitt trigger on Vybrid pin in MQX?

I am using a Vybrid VF5x, and some of the inputs that I want to sense may be slowly-changing. Therefore I would like to enable the Schmitt trigger functionality on those specific pins.

I am using the lwgpio framework. Is there a way to enable Schmitt triggers using this?

If not, what is the recommended way to enable Schmitt triggers?

Dear Ricahrd,

In Chapter 5 Input/Output Multiplexer Controller (IOMUXC), in the pad configuration tables, there is a special field, number 9 and called HYS, which selects the desired input type - 'CMOS' or 'Schmitt trigger'.
