.NET CORE 6 - Injecting IDbConnection... is it good practice?

I have an api to build and using dapper - IDbConnection. Atm i have an instance of IDbConnection for every db call and i dispose it immediately:

public async Task<IEnumerable<T>> LoadData<T>(
            string sqlQuery,
            string connectionId)
        {
            using IDbConnection dbConnection = new    SqlConnection(_configuration.GetConnectionString(connectionId));

            return await dbConnection.QueryAsync<T>(sqlQuery);
        }

public async Task<IEnumerable<T>> LoadData<T>(
            string sqlQuery,
            string connectionId)
        {
            using IDbConnection dbConnection = new    SqlConnection(_configuration.GetConnectionString(connectionId));

            return await dbConnection.QueryAsync<T>(sqlQuery);
        }

Since i only have one sql database to query, is it good practice to inject the dbConnection on startup? Will this cause any performance issue since the connection will stay open all the time (if i'm correct)?

I would probably inject a connection factory, or connection pool But i often deal with multiple databases
