No, it does not.

sounds like you haven’t read it closely.

Article vii sub 5
5. Each Contracting Party shall, at the time when the present Treaty enters into force for it, inform the other Contracting Parties, and thereafter shall give them notice in advance, of a. all expeditions to and within Antarctica, on the part of its ships or nationals, and all expeditions to Antarctica organized in or proceeding from its territory; b. all stations in Antarctica occupied by its nationals; and c. any military personnel or equipment intended to be introduced by it into Antarctica subject to the conditions prescribed in paragraph 2 of Article I of the present Treaty.

article x
Each of the Contracting Parties undertakes to exert appropriate efforts, consistent with the Charter of the United Nations, to the end that no one engages in any activity in Antarctica contrary to the principles or purposes of the present Treaty.

all expeditions must be approved by the host nations, and then given to the other member nations in advance of them for subsequent approval.

Lots of Flat Earthers claim it as a fact.

flat earthers are, largely, not real. they are agents and or products of a psyop. they repeat that “fact” because it was presented to them as such, like most all other claims of fact one might encounter.

earnest flat earth researchers may, of course, claim it as fact and have evidence to support their claim (a fact is merely one type of claim, after all). however, wether that fact is true or false doesn’t change the shape of the world - nor does the shape of the world depend on it being true (wether flat, round, or any other shape).

as i said, it’s all red herring to discussion/determination of the shape of the world anyhow.
