C# ORM with no sql DB

Question

I want to use NoSQL databases with ORM (PetaPoco, Dapper, EF Core) in my .NET 6 app. PetaPoco use connectionString and providerName, I just need to install the provider and that's it? The same situation with EF Core? I didn't find the information I needed in the documentation. Is there a list of supported databases?

PetaPoco:

using PetaPoco;
using WebAPI.Models;

namespace WebAPI.Data
{
    public class PetaDb
    {
        private readonly Database db;

        public PetaDb(string connectionString, string providerName)
        {
            db = new Database(connectionString, providerName);
        }

        public IEnumerable<EmployeeModel?> GetEmployee(Func<EmployeeModel?, bool> predicate)
        {
            
            return db.Query<EmployeeModel?>("SELECT * FROM Employees").Where(predicate);
        }
    }
}

Is it enought to install provider for MongoDB for example and just pass as a parameter in constructor or not?

Dapper:

using Dapper;
using System.Data;
using System.Data.SqlClient;
using WebAPI.Models;

namespace WebAPI.Data
{
    public class DapperDb
    {
        private readonly string _connectionString;

        public DapperDb(string connectionString)
        {
            _connectionString = connectionString;
        }

        public EmployeeModel? Get(Func<EmployeeModel?, bool> predicate)
        {
            using (IDbConnection conn = new SqlConnection(_connectionString))
            {
                return conn.Query<EmployeeModel?>("SELECT * FROM Employees").FirstOrDefault(predicate);
            }
        }
    }
}

I just pass connectionString and always open new connection, is it enought to create MongoDB client and use Dapper or not?
