Is it possible to make games for PlayStation 5 without DevKit Hardware?

Hi
As a solo game developer, I am making games for PC. But I have been thinking about publishing the game for PlayStation 5.

Before, I did not know about the process of making games for the PlayStation 5, But I realized that I must be a partner in PlayStation. That is not a problem in this case.
You can become a PlayStation partner as a sole trader.

The question that bothers my mind is, is it not possible to make a game for PlayStation 5 without Dev-Kit Hardware?

Doesn’t PlayStation provide the possibility to upload the built game in a space and test it in the regular PlayStation 5 console?

Do all the people who publish their game on PlayStation store have Dev-Kit hardware?

Are the tests we do in UE5 not enough for simple games?

I will thank you in advance for the advice
