Supporting beam a few inches above concrete footings

I’m building a deck that is low to the ground. I’m having trouble figuring out how to support the beam that is only a few inches above the concrete piers.
I tried using the Simpson strong tie post beam and post cap, but it looks awfully silly with 6×6 posts that are only 1-1/2” to 2” in height. There isn’t enough wood to properly nail and secure the brackets to the wood. And the wood easily splits.
I can’t seem to find another solution. The adjustable brackets I found that would connect from the concrete directly to beam don’t seem to support the beam width of 4-1/2” (consists of three 2×10).
If I were to go back I would have tried to regrade the area to give me a few more inches. And I don’t want to flush mount the joists to the beams as I’d lose the cantilever area.
Any advice? Thank you.

I would think about shimming under the beam.
Cut treated 2x long wedges that are a foot or so long, and a bit wider than the largest gap you have.
insert these from opposing sides. (I would also use some suitable construction adhesive). After it sets up for a day, trim the excess if you like, or leave it under the deck.
You can do this a couple times over each Pier if you like, there are support guidelines for how long the beam needs to be supported.
If you need uplift resistance, some framing connectors from the pier to the beam should be available.
Supporting beams several inches above the concrete foundation usually require the use of adjustable column bases or piers. They provide a stable connection between the beam and the foundation, allow height adjustment, prevent direct contact with moisture, help prevent rot, and extend the life of the structure.
