Currently, I am installing Boost using Chocolatey,
choco install -y boost-msvc-14.2 --version 1.74.0
This installs both the 32 and 64-bit version of the library. I believe I don't need the 32-bit version, and to save space and time (each version is ˜150MB, and the files are downloaded separately); I would like to download only one of the two versions.
$ choco install -y boost-msvc-14.2 --version 1.74.0
Chocolatey v2.3.0

Installing boost-msvc-14.2
...
How can I download (or at least install) only one of the architectures (64bit)?
Is there a command line for choco to install only one of the two versions?
(other scripted ways in Windows to install Boost are welcome)

Looking at the package you have specified (boost-msvc-14.2), it intentionally installs both x86 and x64 versions of the libraries:
This package includes Boost headers and libs compiled with Visual Studio 2019 for 32bit and 64bit Windows.
There is no way to control this beyond modifying the package, or talking to the package maintainer to add package parameters (or handling for the x86/x64 arguments) to influence it.
