What egpu setup for dual LG Ultrafine 4K 24" and Caldigit TS3?

I have a Macbook Pro 13 2020, 10th gen i5, 4 TB3 ports. I'm currently using it with 2 LG Ultrafine 4K monitors and a Caldigit TS3 dock.

Current Setup: MBP 13 <==> Caldigit TS3 <==> Ultrafine 4K #1 <==> Ultrafine 4K #2

I want to use an egpu that has 2 TB3 ports so that it can daisychain from MBP 13 to Dual Ultrafine 4K and allow me to control sound and brightness from the laptop.

Hypothetical Setup 1: Caldigit TS3 <==> MBP 13 <==> EGPU <==> Ultrafine 4K #1 <==> Ultrafine 4K #2

Hypothetical Setup 2: MBP 13 <==> EGPU <==> Caldigit TS3 <==> Ultrafine 4K #1 <==> Ultrafine 4K #2

I'm not sure which setup is better so I hope someone can tell me.

Akitio Node Pro and Blackmagic EGPU are both no longer available in Australia.

After checking out another similar thread, I'm strongly considering the Akitio Node Duo along with a Powercolor Red Devil 5700 XT.
Does anyone have any experience on the Akitio Node Duo noise levels?

What is the best gpu for an egpu setup before seeing noticeable diminishing returns on performance due to the bottlenecks of thunderbolt or egpu?

Apparently I'll need a GC-Alpine Ridge card in the second slot of the enclosure since the first TB3 port supports 60W for the laptop, while the second TB3 port only supports 15W which may not be enough power for two Ultrafine 4K monitors. Correct me if I'm wrong on that.

I'm not sure if the Alpine Ridge card will be able to daisychain both monitors with a caldigit ts3 since the monitors and the ts3 dock use titan ridge.

To do: Create my signature with system and expected eGPU configuration information to give context to my posts. I have no builds.

Avoid GC-ALPINE RIDGE solution since you won't get USB, audio, brightness control from that (no software exists yet to enable PCIe tunnelling).

The 4K displays don't need Thunderbolt unless you need USB 3.0 from their USB ports. You can get USB 3.0 from elsewhere.

Therefore : MBP 13 -> eGPU -> two Belkin Charge and Sync cables -> two 4K displays
                         \-> CalDigit

Keep the CalDigit and eGPU on separate sides for best performance.

Mac mini (2018), Mac Pro (Early 2008), MacBook Pro (Retina, 15-inch, Mid 2015), GA-Z170X-Gaming 7, Sapphire Pulse Radeon RX 580 8GB GDDR5, Sonnet Echo Express III-D, Trebleet Thunderbolt 3 to NVMe M.2 case

I've just ordered the Razer Core X and 5700 XT Red Devil. I also have two Moshi 5K cables from 2 months ago that was used for connecting both Ultrafines to my gaming desktop.

I'm not fussed about having USB or audio connections from the monitors since there is the Caldigit TS3. Previously when using my Windows gaming desktop with the Ultrafines, I was able to use ClickMonitorDDC software to control the brightness without the keyboard. I'm hoping the MonitorControl app for Mac will be able to the same as the Windows equivalent ClickMonitorDDC.

Should I bother getting the Belkin Charge and Sync cables or will the Moshi USB-C to DP cables be adequate for my use case?
