is it possible to create an Invoice from a SetupIntent?
No, but you could pay an Invoice with the Payment Method a confirmed Setup Intent generates

Or is there a way to pay an Invoice with a manually charged PaymentIntent?
Unclear what you mean by 'manually charged'

Ah sorry I meant to say manually captured: Currently I'm setting up a SetupIntent to then create a PaymentIntent. Then the PaymentIntent is captured with an amount that is most of the times lower than the original amount.
And now I want to additionally create an invoice for the payment.
Do you know a way to accomplish that?

You'd just create a Invoice via the API and mark it as paid out of band. But why not just create the Invoice first, which will generate a Payment Intent for you?

I could not find anything about changing the amount of an Invoice after it was created. Did I miss something?

Also did not find anything about 'blocking' a certain amount of a PaymentMethod before capturing it, like with PaymentIntents.

Yes you need a Payment Intent object to place an auth/hold on a card

But I don't see any possibility to update the amount of the Invoice
