MVC - Trying to use Interface Segregation Principle in my project (SOLID)

Question

I have a method that is responsible for uploading files when trying to add a product. The problem is that I don't use Interface Segregation Because in the method I only use one property that belongs to the product and not all of it as an example:

Model Product:

public class Product : BaseEntity
    {
        public string? Description { get; set; }
        public int CategoryId { get; set; }

        public string PhotoUrl { get; set; } = string.Empty;

        [ForeignKey("CategoryId")]
        public virtual Category Category { get; set; } = null!;
    }

Service:

public class PhotoService : IPhotoService
    {
        private readonly IWebHostEnvironment _environment;
        public PhotoService(IWebHostEnvironment environment)
        {
            _environment = environment;
        }

        public async Task<string> UploadPhotos(IFormFile file, Product product)
        {
            string wwwPath = _environment.WebRootPath;
            var path = Path.Combine(wwwPath, "images", file.FileName);
            if (file.Length > 0)
            {
                using var stream = new FileStream(path, FileMode.Create);
                await file.CopyToAsync(stream);
            }
            return product!.PhotoUrl = file.FileName;
        }
    }

Here I use the Product parameter but use only one property which is the PhotoUrl

I tried to do it using DTO or string but it didn't help me at least how I tried
