I see a initial problem in your request: when you speak about LACP Port Trunking is implicit that each Port Trunk you consider (which other brands can call "Interface Bonding" or "Teaming") requires a number of member physical interfaces equal or greater to two (the upper limit depends, Switch side, by Switch hardware/software limits related to Port Trunking)...otherwise referencing LACP Port Trunking to a link made using just one single physical interface (read for semplicity: one cable) is - IMHO - a non sense. That's a Trunk, nothing more.
So if you have two NAS, each one with only one 10G physical interface, you're pretty limited to implement a single link Trunk not a LACP (or a Non-Protocol) Port Trunk...clearly that is valid on each NAS you're considering.
If otherwise you have two NAS equipped with, each one, two free 10G physical interfaces then you can create - on both ends (Switch and NAS) - a Port Trunk with those two 10G physical interfaces as member ports...so, Switch side, you shall end up with two Port Trunk(s) (each one made of two 10G member ports) for a grand total of four 10G physical interfaces used on Switch side and one Port Trunk on each NAS (made with its two 10G member ports).
