Conceal Carrying at Arlington Cemetery

After the unfortunate recent incedents in Canada and NY, I know that security has been beefed up At Arlington National Cemetery. Is there any federal law prohibiting a conceal carry permit holder from carrying at the Arlington National Cemetery?

National Cemeteries that come under Dept of Veterans Affairs.

38 CFR § 1.218 § 1.218 Security and law enforcement at VA (Veterans Affairs) facilities.
(a) Authority and rules of conduct. Pursuant to 38 U.S.C. 901,
the following rules and regulations apply at all property under the charge and control of VA
(and not under the charge and control of the General Services Administration) and to all persons entering in or on such property. The head of the facility is charged with the responsibility for the enforcement of these rules and regulations and shall cause these rules and regulations to be posted in a conspicuous place on the property.

(13) Weapons and explosives. No person while on property shall carry firearms, other dangerous or deadly weapons, or
explosives, either openly or concealed, except for official purposes.

Thanks for the reply.
