But when executed it use sources files in /etc/apt/sources.list.d/. So i want this command only read the specified source file. How to do it ?

You are looking for Dir::Etc::SourceParts:

apt-get update -o Dir::Etc::SourceList=/etc/apt/security.sources.list -o Dir::Etc::SourceParts=/some/valid/dir/false

You can use whatever instead of false, you can use a valid empty directory if you want.
