Thanks to this comment from
Olga Mulina, show a way to upload IDE Backend installer from local.
- download the Linux IDE distribution from this page (it's Linux because the OS in the container is also Linux, we don't support Windows-based containers);
open the Search Everywhere feature in the IDE (double-Shift) and type
registry;
- enable the
devcontainers.use.separate.project.panel key:

- after that, on the dev container building process, you should see the following interface:

- here you should select the Installation options link and then the Upload installer file action from the dropdown menu.
It save my days, may also save yours.
