Yes, you should be able to set any `Content` for section.
Just use obj2yaml on that binary, it should produce a workable yaml (which you might want to reduce though).

e.g. this is yaml produced from `cfi.elf-aarch64` input also used in this test file:

```
  - Name:            .plt
    Type:            SHT_PROGBITS
    Flags:           [ SHF_ALLOC, SHF_EXECINSTR ]
    Address:         0x00000000000002D8
    AddressAlign:    0x0000000000000008
    EntSize:         0x0000000000000010
    Content:         F07BBFA9F00000F011FE47F910E23F9120021FD61F2003D51F2003D51F2003D510010090110240F91002009120021FD6
