Is there a clksrc_div3byn for okCPLL22150?

I am working with XEM7001, and I want to use all three clocks from PLL22150.
I am able to configure the clock 1 and clock 2 frequency by ClkSrc_Div1/2 in the ok.py, but I could not find anything for the clock 3 (sys_clk3).
How do I configure the frequency from VCO for this clock 3?
