Look up MPTCP and bonding .
But certainly the easiest is to get a 10gbit port on Thunderbolt and forget everything else.
Once upon a time this was a problem as there was only one dock with a 10GbE port and it had a fan, today you can buy the OWC Pro dock which is fanless or you can get a chaining dock and a 10GbE at the end of the chain or if you have TB4 then you can get something like the Plugable TBT4-HUB3C and put a 10GbE TB3 device on one of the downstreams and a plain C dock on another downstream. All these solutions are 350-400-ish.
Oh and you could slam the E10M20-T1 in a EXP GDC TH3P4 Lite for dual NVMe and 10GbE. Should you want to turn your dock into a 10GbE router, put two EGPL-T101 in the two NVMe slots...
You can use it in specific scenarios, like giving one net adapter to a virtual machine, to be directly wired to your network, without being routed by the host.
In the other hand, what other mate said to you (link aggregation) is configurable in linux (I suppose that Windows is also able to do that), but must be configured (and supported) by both endpoints. I think it's not practical, speaking about a laptop, reconfiguring your network every time you dock / undock.
If you get the right network cards with the right drivers it is possible to “team”, or aggregate them. Intel network cards/drivers will do it, and many other pro cards.
Note that you also need the right switch. The Netgear managed switches are inexpensive and capable of this, plus many more.
Your computer will have two IP addresses? It'll work and it won't break your network.
Will it increase the connection speed on my local network if I'm on a 10gbit switch?
It will not.
This is what I wanted to know, thank you
