Yes. Looking at
https://github.com/Chadster766/McWRT/wiki/Linksys-WRT1900AC-Serial-Port
it seems to be jumper JP10.
1 - GND
2 - RX
4 - TX
What i don't know is, is Rx and Rx from the perspective of the board
or the host?

We could put a partition in the gap, to make it usable. You could for
example place the DT blob there. I've not actually checked the version
