LT8650 Minimum Inductor Calculation

I am looking for guidance on calculating the minimum inductance required to prevent subharmonic oscillation on the LT8650.  I found the mention of APP NOTE 19 (which is an amazing reference) and the details there.  I was not able to locate the Sx Voltage ramp parameters for the 8650 in the datasheet though.  Could you please provide some guidance here?  In the worst case the converter will be outputting 12V from a 13.2V supply, so close to 90% duty cycle.
