I don’t think there’s such an option available, but I could be wrong.
I have a passion project and I don’t want people donating me money, with illusions, that it will increase my development speed
I like to think that in the indie world, donations are to support devs, and not to make them work faster. My suggestion would be, as you mentioned, to include all the details in the description. Make sure to be clear about what the project is about, and if there will be any change if more people donate.
At the end of the day, donations are always “no strings attached”. Otherwise they wouldn’t be donations, but bought labor.
