I got excided looking at this hoping there was a laptop with out a screen. I'm totally blind so the power draw of a screen is pointless. I currently use my ROG Alli with a Bluetooth keyboard to connect to my more powerful laptop which has a keyboard that's going bad. While this setup works well and the battery life is pretty good it would be much nicer if I didn't have to put a keyboard on my lap, and the Alli on a table. At least the Alli doesn't need to be somewhere where I can look at it.
I'm not sure if this would work for you, but there are inexpensive devices that plug into an HDMI port. They appear to the computer as a monitor. I use them for screen sharing to a remote display, but they should enable to think there is a monitor attached. It negotiates the display information as if it was an actual monitor.
Google "headless macbook", there is a community of people making macbooks without displays.
The idea started from recovering macs with a broken display and using them like a mac mini. It's possible to find "broken macs" for cheap in second hand market and if the problem is only the display you can go for the headless approach and have macOS with Apple Silicon for very cheap.
Apple Silicon has outstanding battery life, without a screen I would think even more.
You can get some other antennas, place them in the chassis and connect them to the network card. On (at least the first run of) MNT Reform laptops that's how it's done.
He says he uses the Khadas Mind / Khadas Mind 2 which is a mini pc that has a battery so its pretty much a screenless laptop. Not clear the battery is very large but he uses an external one too as its usb c powered.
Since you mentioned the ROG Ally, if you are looking for a handheld without a screen (basically a controller with a built in computer) you may like the Tecno Pocket Go.
Also, great pun with being blind and "excited looking at this".

I'm also blind and this is not a pun. No one blind I know would change their usage of language to avoid using vision verbs for the sake of underlining how blind they are.
