Can't get HP laptop to connect to dual monitors using HP Docking stations

[ITGeek1]

I have this HP laptop and i'm trying to connect to dual external monitors. I've tried two different HP Docking stations (USB-C Gen 5) and a HP thunderbolt G2. I've connected them via USB-C, HDMI and in either case the laptop does not recognize the external monitors. Any ideas?

I can not find its specs but is has same PORTs as the following machine

It ONLY has 1 hopeless SuperSpeed USB Type-C® 5Gbps signaling rate port which does NOT support Alt mode nor Power Delivery. You can NOT use it to

• Charge your machine,
• Connect to an external monitor with/without hub/dock/adapter (some hubs may have builtin chip to support this)

If you wish to connect 2 external monitors (total 3), you can use

• Monitor 1: HDMI direct cable,
• Monitor 2: Using a Displaylink Certified USB-A to HDMI adapter such as

Option: You can use UAB-A dock such as    https://www.amazon.com.au/HP-3005PR-USB-Port-Replicator/dp/B008KMDVPQ
