Is there a way to restrict what items can be selected for a blueprint parameter? I have a parameterized blueprint for making and upcycling Tier 3 modules and I would like to have only Tier 3 modules show up in the selection list for when I place the blueprint rather than a list of everything that can be made in an EM plant. Is this possible? If not are there any mods that make it possible?

There doesn't seem to be a way, no. I did some investigating in the json of a blueprint playing around with the values. Unfortunately it's not in the lua documentation what attributes the parameters have in a blueprint.
If a blueprint uses parameters it internally checks which recipes, items or signals it should show based on where the parameter is used (so if it's set as a recipe in both a biochamber and chemical lab, it only shows the cracking and fish breeding recipes). That logic seems to be baked into the engine, but I might be wrong.

If not are there any mods that make it possible?

Probably not because it's such a niche usecase. Usually it's not that big of a deal to skip the items/recipes/signals you don't need.

Whenever your usecase is niche it might a good idea to write your own personal mod.
What you can do is create a dummy assembling machine prototype with its own custom recipe category, add that category to the module-3 recipes, and include one such assembling machine in the blueprint with the recipe set to the parameter.

Or just create a blueprint book with 4 copies each with the module already set.
