I believe COLGeek is correct. 144Hz should be available, but definitely not at 4K.
It is practically unheard of having a 144Hz 4K display. Even the most powerful setups wouldn't be able to run it, and that's assuming it's a discrete GPU with an external monitor using the newest HDMI or DisplayPort connection.
The technology isn't quite there yet, and even if you somehow truly do have a 4K monitor capable of a full 144Hz @ 4K, your built in graphics card was not designed to handle that threshold.
And you can't exactly pull out the 2070 in your laptop... so you won't be getting 144Hz at 4K, sorry bud. Most GPU's don't even support HDMI 2.1 yet, and I doubt there's any connection inside your laptop capable of pushing that kind of bandwidth.
