How to join two files with bash & remove duplicates?

Question

I would like to know how to join two files on one column and remove the duplicates. Some examples first.

File1:

SERVER1; Deployed; Infrastructure
SERVER2; Deployed; Infrastructure
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
SERVER5; Deployed; Infrastructure

File2:

SERVER1;
SERVER2;
SERVER5;

Expectation:

SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure

Tried commands like: sort File1 File2 | uniq > File3, but it only returns me the joined output, as it does see every column as unique, output is like:

 SERVER1;
 SERVER1; Deployed; Infrastructure
 SERVER2;
 SERVER2; Deployed; Infrastructure
 SERVER3; Deployed; Infrastructure
 SERVER4; Deployed; Infrastructure
 SERVER5;
 SERVER5; Deployed; Infrastructure

Then tried to remove the duplicates from what I got above with command awk -F";" '!_[$1]++' File3, but seems like it only remove one duplicate line and left the other be:

SERVER1;
SERVER2;
SERVER3; Deployed; Infrastructure
SERVER4; Deployed; Infrastructure
SERVER5;

I would like to check on duplicates and remove both duplicate and the server itself, do you have any suggestions?
