2023 20” light bar lower grill

I ended up getting an Auxbeam 20” light bar for dirt cheap on an auction site. I was considering mounting this into the gap in the lower front bumper. I see there are pre-fab kits with a mounting bracket- but does anyone sell the bracket without a light bar included?
Google, fb, and searching here did not turn up many results outside of the larger upper grill light bars.

Also, any opinions on switch panels? Auxbeam wired vs Garmin switch wireless vs M&R automotive wireless? Or others! Thanks!
