Set not required property ASP.NET Core SQL Server - sql-server

Question

Some of the string properties in the class do not have a [Required] attribute, and when migrating it to SQL Server, it adds a NOT NULL property. I have revised the code so much but didn't reach any solution yet.
public class Stores
{
[Key]
public int StoreID { get; set; }
[Required]
[Display(Name = "Store Name")]
public string StoreName { get; set; } = string.Empty;
[Display(Name = "Store Bio")]
public string Bio { get; set; } = string.Empty;
[Display(Name = "Store Description")]
public string Description { get; set; } = string.Empty;
}
This is the SQL code generated
CREATE TABLE [dbo].[Stores]
(
[StoreID] INT IDENTITY (1, 1) NOT NULL,
[StoreName] NVARCHAR (MAX) NOT NULL,
[Bio] NVARCHAR (MAX) NOT NULL,
[Description] NVARCHAR (MAX) NOT NULL,
[BrandsBrandID] INT NULL,
[CategoriesCategoryID] INT NULL,
[CollectionsCollectionID] INT NULL,
[ProductsProductID] INT NULL,
CONSTRAINT [PK_Stores]
PRIMARY KEY CLUSTERED ([StoreID] ASC),
CONSTRAINT [FK_Stores_Brands_BrandsBrandID]
FOREIGN KEY ([BrandsBrandID]) REFERENCES [dbo].[Brands] ([BrandID]),
CONSTRAINT [FK_Stores_Categories_CategoriesCategoryID]
FOREIGN KEY ([CategoriesCategoryID]) REFERENCES [dbo].[Categories] ([CategoryID]),
CONSTRAINT [FK_Stores_Collections_CollectionsCollectionID]
FOREIGN KEY ([CollectionsCollectionID]) REFERENCES [dbo].[Collections] ([CollectionID]),
CONSTRAINT [FK_Stores_Products_ProductsProductID]
FOREIGN KEY ([ProductsProductID]) REFERENCES [dbo].[Products] ([ProductID])
);
