2 monitor set up on MacBook Pro with just 1 unused ThunderBolt port

I started work at a new organization and have been provided with a 2017 13" MacBook Pro with 2 Thunderbolt ports. Those are the only two ports on the device apart from a 3.5 mm jack. One of the TB port is always occupied by a YubiKey which is a security device which needs to be plugged into the laptop for me to access office resources. I have read that Macs don't support daisy chaining so is there any way that I can have a 2 monitor set up with just 1 TB port ?

Macs do support daisy-chaining over Thunderbolt. Depending on whether your monitors can be daisy-chained, you can either daisy-chain them or use a USB-C or Thunderbolt Hub to gain additional ports. You could also plug in your YubiKey into one of the monitors if it has a built in hub.
