have to open lid to connect monitors

Hi guys

I'm having an issue with my Dell dock, and for some reason I always have to open my laptop lid to reconnect to my monitors.

For example, when I come home from work, my MacBook is usually closed and sleeping.
If I plug it in with power and USB-C cable to connect it with my dock, nothing gotta happen.
With my ThinkPad, I can simply plug it in and maybe hit the space bar for a few times on my bluetooth keyboard to activate it.
And then both of my monitor (via HDMI) will light up, and Windows login will be there.

However, with my MacBook, I must open the lid and login in and then wait for the monitors to have signal.
This is also true if I reboot my MacBook in a clamshell mode.
I must reopen the lid so that my monitor could be connected.

I saw that folks have mentioned that updating firmware might solve the issue:

However, there does not seem to be any update for my dock from Dell at all.

This is my first time using a DisplayLink dock with a MacBook, and I wonder what the cause of my problem is.
Is this a dock's issue? Or maybe a macOS issue?

Is there any way to solve this? Should I change some system settings or something?
Or maybe there are some third-party apps for this?

My system info:

Laptop: MacBook Air (M2, 2022)
Dock: Dell D3100
macOS: 12.5.1
DisplayLink manager: 1.7.1

Thanks in advance
