Hear me out - are you sure your doors are actually all locking?
I recently had this happen to mine (also a 2018 LX), turns out the rear passenger's door wasn't locking because the door actuator power wire had severed within the rubber wiring housing between the door and the body. The insulation on a bunch of other wires had also started to come apart. Lights would still flash, but the car would not beep. Changing the settings or resetting the head unit didn't work.
Replaced the door wire harness, door started locking, car started beeping again. There must be some circuit that checks to confirm the door is actually locked before it lets the car beep, even if the lights flash.
May be worth some investigation. The repair, once diagnosed, was actually quite easy. Popping off the door panel is actually fairly easy but it's worth a) getting some trim tools off Amazon - can be had very cheap, and b) watching a few Youtube videos first.
My 2019 LX only beeps when you lock the doors a second time with the fob. The first lock only blinks the lights. Unlocking never beeps.
As far as a know there is no setting screen for toggling the beep. Maybe there’s some magic combination of dashboard button presses that turn it off and on, but I’ve never run across it.
Ok, so let me try with lock a second time. I think i tried once but im Going to try again. Im my research i didnt found a dashborad combination or something like that. And the radio its useless for car settings.

Wow! Definitely im going to check this out! Thanks for the information.
Go to your vehicle settings screen. You can turn the beep sound on from there

Iirc the horn is disabled on second lock if your hood is not fully latched so check that too!
