No ! Assuming you mean R1/R2/C1/C2 of the Miller schematic, those
values are already set for the comparison frequency (10KHz) of the PLL
phase comparator (U2).

I assume the PLL filter needs to be designed to accommodate a specific oscillator specifications, or maybe it doesn't really matter and can use the default values in the schematic?.
