I’m making a custom TileMap and I need to define if a cell is in view to mark it for drawing.

Not sure what you mean, but there is a node called VisibilityNotifier that you can use for that. It can both check the entire viewport and a camera, quite a useful little node.
What should I do if I don’t create CanvasItem, but I use DrawRect()?

My solution. I didn’t find the built-in method.
func _intersects_viewport(rect: Rect2) -> bool:
var transform : Transform2D = get_canvas_transform()
var scale : Vector2 = transform.get_scale()
return Rect2(-transform.origin / scale, get_viewport_rect().size / scale).intersects(rect)
