SPI Command Line Utility

I am new to Verdin i.MX 8M Plus.
I have a couple of SPI devices and I would like to do low-level SPI reads/writes.
Is there a command line utility to do low-level SPI reads/writes?
Is there a Python SPI library similar to Rasperry Pi SPINCL to use with Verdin i.MX 8M Plus?
