Dynamically Change a dataset based on a filter

Hello, I am almost sure this is not possible, but I am hoping that there is a workaround.

I have four datasets in two areas of concern: two datasets (Math Grades and English Grades) are about School and two are about demographic (Total Population and Land Area).

Goal: When I select "area of concern = School, then the charts Math Grades and English Grades appear", if I select "area of concern = demographic, then charts Total Population and Land Area appear" as in the image below:

Then if a select another area of concern, the charts change:

I tried to create another Table in Power BI to be used as Referece Table like this one below:

Then, I tried to link them on the "Model View" like the image below but it didn't work at all.

Has Anyone done something similar? Observation: the actual datasets have thousands of rows, so I cannot append all the datasets in one single dataset. They have to be separated.

Best regards
