Are F.55 and ES.34 the same?

It looks to me that these two are very similar in what they are trying to say:

https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#f55-dont-use-va_arg-arguments
https://github.com/isocpp/CppCoreGuidelines/blob/master/CppCoreGuidelines.md#-es34-dont-define-a-c-style-variadic-function

They both talk about lack of type safety:
F.55: Reading from a va_arg assumes that the correct type was actually passed
ES.34: Not type safe.

They both provide examples of how passing the wrong thing can be bad.
They also provide more or less the same alternatives:
F.55:

Alternatives
    overloading
    variadic templates
    variant arguments
    initializer_list (homogeneous)

ES.34: Alternative: Overloading. Templates. Variadic templates.

The first one seems more complete as it mentions that these functions are applicable to catch all in overload sets.

Should we remove ES.34 and keep only F.55?

Start in CppCoreGuidelines.md at F.55 and ES.34, reading both rules, alternatives, and examples side by side. Determine whether they are redundant and document the rationale for retaining, revising, or removing one; done means the guideline text and cross-references clearly resolve the overlap.
