You cannot do it. PAD is the only interpreter available for the language behind its code, and it does not support executable files. As @Deenuji correctly pointed out, the flows rely on data stored in the cloud, and are not actually stored locally (except for some cached copies).
If you wanted to create an executable, you would need to reverse-engineer the .dll functions in the PAD directory to find what they actually do as different actions in PAD are invoked, and then possibly copy the code of your PAD flow to your actual executable file. But this would obviously be against the terms of use of Power Automate.
