I am pretty sure that you can have that, too, and for free! 
The WapAx is an exception, it is rather directional, the W stays for Wall, so in the back there is little radiation, the most is projected forward in an angle that is in the 90-120° range, possibly a bit less.

About 5Ghz, you seemingly let the Mikrotik to use whatever channel it sees fit:
/interface wifi
set [ find default-name=wifi1 ] channel.band=2ghz-ax .skip-dfs-channels=10min-cac .width=20/40mhz configuration.country=Canada .mode=ap .ssid=Rivendell disabled=no security.authentication-types=wpa2-psk .ft=yes .ft-over-ds=yes
set [ find default-name=wifi2 ] channel.band=5ghz-ax .skip-dfs-channels=10min-cac .width=20/40/80mhz configuration.country=Canada .mode=ap .ssid=Rivendell disabled=no security.authentication-types=wpa2-psk .ft=yes .ft-over-ds=yes
and there are a few channels on the high end of the 5 GHz band that usually Mikrotik “prefers” but that common devices (possibly also your charger) simply cannot reach/connect to.
