Unfortunately, I don't believe so.
Arduino App Lab is built on the excellent open source Wails framework:
https://wails.io/
Wails does indeed use this flag internally when the WebviewGpuIsDisabled application optiontrue:
(note the application options are defined in the application source code, not command line flags)
However, this is Windows-specific (and also not done in the Arduino App Lab application options ).
There is a GPU-related option for Linux: linux.WebviewGpuPolicylinux.WebviewGpuPolicyNever, and that was explicitly done as a workaround for a bug described similarly to the one you experienced in Arduino App Lab :

### Description
Yesterday my app worked just fine. This morning, after making… no changes to the code, I executed `wails dev` and it resulted in a full gray window. However when I randomly move my mouse on the window I can see the tooltips of my app.
Can't even open the dev tools in the wails window. Works in the browser though (`wails dev --browser`).
My `main.go` does correctly include the assets:
```
//go:embed frontend/dist
var assets embed.FS
```
Wails dev output:
```

### To Reproduce
```
wails init -n testwebkit
wails dev
```
### Expected behaviour
I expect a properly working Wails app window
### Screenshots
`wails dev --browser`
### Attempted Fixes
Remove webkit packages. Break my system. Cry. Reinstall webkit. Reinstall Gnome. No solution.
### System Details
Me:
Kubuntu 22.04
Wails v2.4.1
Vite v3.1.8
Webkit: libwebkit2gtk-4.0-37 libwebkit2gtk-4.0-dev
My co-worker who has the same issue:
Arch Linux (kernel: 6.5.6-arch2-1)
Wails v2.6.0
Webkit: webkit2gtk 2.42.1-1 webkit2gtk-4.1 2.42.1-1 webkitgtk-6.0 2.42.1-1

However, this option is set to linux.WebviewGpuPolicyAlways in the Arduino App Lab application options:
If you are interested in performing an experiment, you could try changing that option and then making a build of Arduino App Lab from source. There is some information on that subject here:
https://github.com/arduino/arduino-app-lab/tree/main?tab=readme-ov-file#building-local-machine
I have been able to reproduce this fault:
I encounter the 'NO BOARDS FOUND FOR ""'problem the second time I attempt to use the "Select Other Board and Port" dialog.
Once you type a query in the search field, it will show results. And if you then delete the query it will show the full list of boards as expected.
I don't remember encountering this problem historically, so I suspect it is a regression introduced in a recent version of Arduino IDE (e.g., 2.3.5/2.3.6).
Note that the 'NO BOARDS FOUND FOR ""'problem is not caused by a lack …
It is tracked here:

topic: code
type: imperfection
### Describe the problem
When I write the name of my board in the "**Select boa… rd**" field of the "**Select Other Board and Port**" dialog, the boards list field only shows the message:
> NO BOARDS FOUND FOR ""
### To reproduce
I am not sure if i am the only one on which this happened
### Expected behavior
The dialog shows the list of boards matching the query.
If the "**Select board**" field is empty, it shows the full list of boards.
