Is there an offline installation of DotNet 3.5 in unattended mode?

Question

.NET

We are talking about automatic offline installation of DotNet 3.5 for Windows 7, 8.x, 10.
First of all, I would like to deal with the offline installation of DotNet 3.5.
Microsoft offers an "offline" installer download.microsoft.com/download/2/0/e/20e90413-712... which still uses the network and does not work without an internet connection. In addition, even when launched with the "dotnetfx35.exe /s" key, it displays a window in which you need to click on the "continue" button, after which the installation continues (provided there is an Internet connection).
An alternative is to use the built-in DISM utility as follows:

DISM /Online /Enable-Feature /FeatureName:NetFx3 /All

but this option again uses an internet connection. The same utility can be used to extract a component from an OS distribution, but this requires the presence of the distribution itself and information about the path in the file system to it, which cannot be universal.
An alternative offline installer .Net Framework 3.5 offline Installer was found on the net https://sourceforge.net/projects/framework-3-offline/ but it confuses the presence of a 7z-archive with a password in the distribution kit, it seems to lack automatic installation mode , the author of the distribution does not answer questions in the forum.
So, does anyone know a universal way to install DotNet 3.5 in silent mode?

DotNet 3.5 is not installed on Windows 10, and as far as I remember 8.x, here it is included as a feature through additional components. About the 7-ki wrote above
