How to efficiently migrate EF linq queries to Dapper?

I'm trying to migration EF to Dapper and I'm looking for a better and efficient way on how to migrate existing linq expressions "IQueryable" to use Dapper.

Ex:

public class MyDbContext : DbContext
{
    public DbSet<MyEntity> MyEntity { get; set; }
    +20 more entities..
}

// Inside repository
using (var context = new MyDbContext())
{
     context.MyEntity.Where( x => x.Id == 1) // How can I easily migrate this linq to Dapper?
}

The above code is a simple example only of what I'm trying to migrate. Some of those queries are mix of simple and complex. Currently, I have 20+ repositories and 20+ DbSet in MyDbContext that used that kind of approach inside repositories.

I searched in the internet and I haven't found a better approach. So far the only way to do this is to convert linq into query string one by one and use it in Dapper. It is doable but tedious and huge effort. Performance is my biggest concern why I'am migrating to Dapper.

Does anyone has a better way to do this than what I'm currently thinking?
