The Latitude 3510 was released in 2020. I doubt it is a 32-bit
architecture, like early Pentiums.

I recommend turning SecureBoot off.
- UEFI
* GPT = on
* SecureBoot = off
And legacy modes, like BIOS legacy = off.
In SecureBoot, the only thing that is attested are the disk images.
There's no guarantees about the program once it is in-memory and
executing. What's being executed in-memory is the important thing.
The biggest accomplishment SecureBoot achieved under Windows 8 was
locking out other operating systems. And that did not last very long.
If you are having trouble turning off SecureBoot, then you may need to
add a BIOS/UEFI password. Once a password is present, the selections
to disable SecureBoot become available on some hardware, like Acer
laptops. Once you disable SecureBoot, you can remove the password so
you don't have to write it down.
