How to stop `Format` from evaluating when doing `Put`/`Export`?

Question

If I do

Format[$hello, StandardForm] := "world"

then

Put[HoldComplete[Format[$hello, StandardForm]], "file.m"]

or

Export["file.m", HoldComplete[Format[$hello, StandardForm]]]

file.m will contain

HoldComplete["\"world\""]

How do I get literally

HoldComplete[Format[$hello, StandardForm]]

in the exported file?

Answer 1

Block[{Format},
   Put[
      HoldComplete[Format[$hello, StandardForm]],
      "file.m"
   ]
]

FilePrint @ "file.m"
test = Get @ "file.m"
FullForm[test]

Answer 2

Export["file.m", FullForm@HoldComplete[Format[$hello, StandardForm]], "String"]

works, but all operators will be eliminated because of FullForm:

FullForm@HoldComplete[Format[$hello, StandardForm]*2]

HoldComplete[Times[Format[$hello, StandardForm], 2]]
