Which version support miniPCIe?

I recently bought Compex MMZ531 :https://www.compex.com.sg/product/mmz531/

It has got wle650v5-18A 11ac chip. I tried the latest version LEDE on it by selecting the ath10k kernel module.

Its still not able to recognize the 11ac firmware unfortunately.. I was told by their team that its because of lack of miniPCIe support.

Could anyone let me know is there something that I am missing out ?

Latest LEDE version for what board?

It is compex wpj531

This board has PCIe enabled:

I suppose you have the same problem as @user3097019
