as far as I know using the embedded Firebird database should be possible, but you will need to make the Firebird driver assemblies known and available. You should be able to do so by adding a
<add name="FirebirdClient Data Provider" invariant="FirebirdSql.Data.FirebirdClient" description=".NET Framework Data Provider for Firebird" type="FirebirdSql.Data.FirebirdClient.FirebirdClientFactory, FirebirdSql.Data.FirebirdClient, Version=18.104.22.168, Culture=neutral, PublicKeyToken=3750abcc3150b00c" />
configuration file entry to you app.config. This tells the .NET runtime what to use when looking for a ADO driver for firebird. To use the embedded version, you will need to specify that via the ServerType=1 in the connection string (see https://www.connectionstrings.com/firebird/
Don't forget to put the FirebirdSql.Data.FirebirdClient assembly into you assembly folder!
