adding bsm, acc, and comma ai with just the acc switch and comma ai open pilot

[Rusty_ADV]

I have a 21 1500, has the 12" center stack(W/O LKA), forward collision warning, and the trailer back assist, wanting to add bsm, acc, and comma ai. I believe this has the hardware I need minus the comma ai and the acc switch. trailer back assist has the ability to turn the wheel and has radar to detect the trailer. With this comma ai should have everything it needs to steer and bsm should be able to see objects. with forward collision avoidance, it should have what i need for adaptive cruise control, minus the switch. AI have alphaobd to enable the options, am i missing something?
I found similar post, but none with the exact recipe I'm after.

The following is to be used as a guide on how to install ACC, FCW, Lane Assist, Auto High Beam headlights and rain-sensitive wipers in your 5th Gen Ram 1500, also known as the Advanced Safety Group. I’ve also included a guide at the end of this document on how to install blind spot monitoring. Obviously, I cannot guarantee this will work on your truck, but I am confident it will. I was able to install all these features on my 2019 Ram Lonestar which originally came with an 8.4" Non-Nav Unit with Dual Climate control. I believe this can be activated on any 5th Gen, but I’m literally the...

this is similar to what I'm trying to accomplish, what im asking is is it true that i have the needed hardware already installed in the truck and will the comma ai work without getting the center stack for the lka button

You have the DASM already if you have FCW+ (which sounds like you do). But like post #2 says, you need the ACC button and the HCU/ABS. You do not need the LKAS button, but it does need to be enabled if you want to use it with the Comma.
