Need an adapter from new Mac Pro HDMI to Dual Link DVI with Apple Cinema Display

Currently, I am running my brand new Mac Pro with a couple of older displays that both need dual link DVI. I am using 2 Thunderbolt ports to drive them. Everything looks great but I would like to try to drive these older displays with the HDMI outputs on the Mac Pro. This is the adapter I am currently using: https://www.amazon.com/dp/B08B7FSVTL?psc=1&ref=ppx_yo2ov_dt_b_product_details Is there another adapter that will work as well for the HDMI ports on the Mac Pro?

Thanks.

Mac Pro, macOS 10.13

There are two cases: 1920 wide and less, over 1920 wide.

For 1920 wide or less, you can use an adapter from HDMI to Single-Link DVI for less money. HDMI and DVI are both 5 Volt signal levels and compatible signals. The adapter for single-link DVI from HDMI is 'just wires'.

For over 1920 wide, the interface splits into two sets of color signal-pairs and requires a Dual-Link adapter like the one you have or a very similar one. Or an adapter from HDMI to Dual-Link DVI (rare and more expensive).

the difference is whether the center six pins (medium blue) are active. They are required for display wider than 1920 wide (dual-Link DVI).

I know that I need dual link dvi, there is absolutely no doubt about that. Both of my displays run at 2560 x 1600. I used these adapters with my old Mac Pro as well.

So, I get they would be more expensive, the question is, do they exist? Does someone make these?
