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

Sorry, but it’s not possible. You must have the PS5 SDK libraries and you cannot have them if you are not registered as PlayStation Developer.
