You must use this Python 2 script to unpack the HDR from EXE and then CodeRush’s PFSExtractor to unpack the HDR into its components.
Is there an compiled version of PFSExtractor?
Yes, at github Releases tab.
the python script gave me
O7010A25.exe_decompressed.hdr
Which I then fed to PFS which gave me a bunch of files:

So I guess I could just proceed to mod?
How do I flash it when done?
The BIOS region of the SPI chip is “section_0_A.25.data” file. Provided that BootGuard is not enabled on your system (check via MEInfo -verbose) and that the BIOS is not write protected (access error when reading/writing), you can use flashers such as AFU or Flash Programming Tool (fpt -bios -f bios_mod.bin).
how to compile .hdr file of dell?
how to use pfsextractor for .hdr file can anyone help?
Suppose your PFSExtractor.exe and hdr file in same folder at d:\tmp, run cmd, change to folder d:\tmp
