I sounds like a job for objcopy. See following objcopy option:
--rename-section oldname=newname[,flags]
Rename a section from oldname to newname, optionally changing the section’s flags to flags in the process.
This has the advantage over usng a linker script to perform the rename in that the output stays as an object
file and does not become a linked executable.
This option is particularly helpful when the input format is binary, since this will always create a section
called .data. If for example, you wanted instead to create a section called .rodata containing binary data
you could use the following command line to achieve it:
objcopy -I binary -O <output_format> -B <architecture> \
--rename-section .data=.rodata,alloc,load,readonly,data,contents \
<input_binary_file> <output_object_file>
