Hi, I'm wanting to know if it's possible to setup an L2 cache for reads and writes on an NVME drive and have my main array a SATA SSD based one as the speeds between the two are vastly different and I'm wanting to use all three levels to get most out of the PC with what I have

Yes, you can use a fast ssd as L2 cache to speed up relatively slow drives.

you absolutely can, I use a NVMe drive to cache an iSCSI volume that I host on my NAS
50/50 read/write

But you specifically use NVME SSD to speed up SATA SSD arrays?

If you're using Linux, tools like Bcache, dm-cache, or LVM with caching can set up your NVMe drive as a cache for a SATA SSD array

PrimoCache does not need to check what drive is used as L2 cache. For it, any drive that Windows can recognize can be used as L2 cache.
