Does it support daisy chaining another Thunderbolt 3 device to the 2nd port? e.g. A 10gbe Thunderbolt network adapter.

Hello. Yes, the OWC Mercury Helios 3S will allow or thunderbolt device to be daisy-chained off the second port of this chassis.

Can you install a gpu card like nvidia into this?

Hello. No this unit does not support GPU's.

is this thunderbolt 4 compatible?

Hello. This Mercury Helios 3S is a Thunderbolt 3 device, but can be used in a Thunderbolt 4 port as 3 is backwards compatible.

Will this work with bootcamp windows 10/11 for a lynx aes16e interface card?

I bought this for my vive wireless pcie wigic card and just googled yours. From what I see so long as you have a thunderbolt 3 port it should work.vyour card should fit. However from the looks of the googled image you may have to keep the casing off. No loss it will still work just no shell.
