PointClamp antialiasing

I have MonoGame 3.8, DirectX.
I am drawing texture with spriteBatch with PointClamp. Zoom is with matrix (e.g. 3x).
spriteBatch.Begin(SpriteSortMode.Deferred, BlendState.AlphaBlend, SamplerState.PointClamp, DepthStencilState.Default, rasterizerState, null, camera);
I am trying multisampling inner pixels of texture. Source situation is on the img 0, no rotation, red line is border of image.
If I am rotating without multisampling, there are jagged borders of big inner pixels (img 1).
Img 2…If I use multisampling parameter in the RenderTarget2D constructor, antialiasing is only applied on border of texture.
Img 3…If I use scaling RenderTarget2D with zoomed matrix. (new RenderTarget2D(Graphics, WindowWidth*upscaling, WindowHeight*upscaling, …) Then I adjust target to the window. I got close to what I wanted to achieve. But the way is little bit cabbage.
Img 4…What I want to get
Any ideas?
