PCI-E External Storage methods?

I have a Meraki MR24 OpenWRT 18.06.4 flashed. OpenWRT is telling me I have no space left when I try to install a package. I got a PCI-E SSD module and a PCI-E USB 3.0 module. Inserted them both and nothing new came in "/dev/". No /dev/sda1 or new MTD devices.
A "dmesg | grep pc"i shows

Is PCI-E storage even supported on OpenWRT?

The PCIe bus on some Atheros chips is not a full implementation. It only has the functionality required to support wifi cards.

Well that stinks. I guess without a USB slot, I don't have any realistic options left. Thanks for the reply though!
