Use inheritance in definitions for json column

Question

I have a column definition that works ok for persisting and querying typed json data

Entities

public class TimeLineDefinition()
{
    public DateTime StartDateUtc { get; init; }
}

public class ProductData()
{
    public ProductData(TimeLineDefinition timeLineDefinition)
    {
        
        TimeLineDefinition = timeLineDefinition;
    }
    
    public int Id {get;set;}
    public TimeLineDefinition TimeLineDefinition {get;set;}
}

Mapping

public class ProductDataConfiguration : IEntityTypeConfiguration<ProductData>
{
    public void Configure(EntityTypeBuilder<ProductData> builder)
    {
        builder.HasKey(p => p.Id);
        
        builder.Property(p => p.StartDateTimeUtc)
            .HasColumnType("timestamp with time zone");

        builder.OwnsOne(  t => t.TimeLineDefinition ,navigationBuilder => {
            navigationBuilder.ToJson();
        });
            
    }
}

This Setup persists the object TimeLineDefinition as json in the column TimeLineDefinition .

I now want to have a type

public class TimeLineDefinitionWithEndDate() :TimeLineDefinition
{
    
        public DateTime EndDateUtc { get; init; }
}

that should persist and read StartDateUtc and EndDateUtc. Is this possible with PostgresProvider in EF?
