Open your file with hex editor to 007C1000h, highlight first character, select block to length 10000h. Copy and save, that is your DMI region.

Can i remove this info and flashing this file without DMI region?
But the file size will decrease, is this not a problem?

Why would you remove DMI? You might just blank it out with FF, but surely will have problems with windows keys. I believe this will not blank out a password if that is your goal. The usual is to copy DMI region to a new fresh BIOS BIN if the laptop won't do the update itself or hung up when updating.

My goal only remove Service Tag from bios.
It´s possible with hex editor?

If you know it, I think you can see it and take it out, but according to hoaca388 service tag is inside an encrypted region in newer dell models and needed for security and region identification. I do not have any programs to find it either.

The attached file is your Original BIOS? I found this Service Tag "24CBBH2" in your dump file, it's correct or not?
Please describe more about your device Problem.
