MUGA Stoic PC3 is the third generation product of a line of low-end laptop computers launched on 2020-08-28, by the Don Quijote discount chain store as a product under its private brand Jounetsu Kakaku (Passion Price).
Due to its poor performance and extensibility, I would not recommend this model in general. There are plenty of laptop PCs in used markets with higher performance, comparable prices and upgradable RAM and storage. You have been warned.
However, if you are stoic enough, you might find some fun from it. I hope I am.
I would like to strongly recommend to read Gotchas before doing risky operations.

Do not disable 512-byte sector emulation on the built-in eMMC.
While the built-in eMMC flash seems 4 KiB native and in fact you can disable 512-byte sector emulation with
mmc disable 512B emulation <device>, don't do this.
If you do so, the vendor UEFI firmware slows down awfully its operation for unknown reasons and you can not boot from eMMC even if you clear UEFI boot entries and reinstall an OS into the device. In my case, it took nearly 11 minutes to load USB stick's GRUB, so does UEFI Setup.
I'd warn you once again: do not disable 512-byte sector emulation. Otherwise, you will experience an unrealistically long startup time a laptop computer sold in 2020.
Do not disable cache on the built-in eMMC.
You can the cache in the built-in eMMC flash by executing
mmc cache disable <device>, but you must guess what is happen then.
Don't do this, especially when you have disabled 512-byte sector emulation for some reasons.
Did you find interesting ways to brick the device?
Please leave a comment. Any recovery method would be highly appreciated, too. We need your brave soul and creativity!
- To select the boot device, press F12 (Fn + F11) during startup.
- To enter UEFI Setup, press F12 (Fn + F11) and then select Enter Setup.
