MSI build - Downgradable options

I'm trying to downgrade the MSI build when we switch over the versions in the API. For e.g. We have installed the MSI build with the version 2.0 in the windows machine. I have to downgrade the version for some reasons and I'm updating the API with 1.0. Can the MSI build be downgraded to 1.0 version with Autoupdate?

I know that only manual installation allows this process to downgrade. Also, if the higher version is installed, we will be getting error when we try to uninstall the lower version. (Attached the image for reference)

Do we have any possibilities to install lower version through auto update process?

Note: Autoupdate is the process where I have added a service to check for the updated version each 30 mins. This API contains the version and the download link. If the version is higher than current installed version, it downloads the new MSI build from the link and tries to install it with the silent installation process. By this way, Higher version of the build is installed in the respective machine. As like the same, if the version is lower than the current version, then I should download the particular version from the download link and then install it in the same machine i.e.) the lower version should be installed over the higher version. But when I try to install the lower version, I get the error as Unable to install because a newer version of this product is already installed.
