A:Answer I don't think that will be possible. Although this dock uses Thunderbolt 3 which can support this, your Macbook air does not. As per EveryMac.com: Apple MacBook Air "Core i5" 1.8 13" (2017*) Specs, 2nd Display Support: Dual/Mirroring* 2nd Max. Resolution: 3840x2160 (4K)* Details: *Although Apple originally only reported that this model could support a single external display up to 2560x1600, third-parties discovered that it actually could support a 3840x2160 (4K) display, and Apple subsequently revised their official documentation to confirm this, as well". There's no mention of support for two external monitors.
