CRC function on SPC56EL70L5

I try to use SPC56EL70L5-DISP(master) to communicate another board(slave) through SPI.
CRC-8 , polynomial, C(x) = x8 + x2 + x1 + 1 , is needed for the SPI last byte.
I attempt to use the SPC56EL70L3 build-in CRC function to check/generate CRC byte.
However the datasheet mentions it supports x8 + x4 + x3 + x2 + 1.
Is it possible for me to use the built-in CRC function?
And how do I configure the CRC reg(CRC_CFG, CRC_INP, CRC_CSTAT)

Thanks for help
