I'm not sure that I understand the question. I think you are asking that if we have an ACL on an interface for blocking traffic, will that ACL have any affect on the ability of the eBGP peer to receive a route prefix of the same subnet from a neighbor.
This answer would be the ACL will NOT block the advertisement but would block the actual traffic.
to block the advertisement you would need to change the import policy on the recieving peer or the export policy on the sending peer.
