Can an iPad Pro MLQ62LL/A accept an SD card?

If you have the right adapter you can read from an SD card, but only properly named photo files (it’s meant to be a way to get photos from your camera onto your ipad)

but there is zero support to write to SD cards and even if you read from them as listed above, it’s only photos or compatible video files

I have never seen any iPad models with an external memory card slot so no, you can't use an SD or microSD card.
