It is possible to some extent, but we must always keep in mind the limitations. If we have a very precisely defined research question and well-founded research assumptions, then in certain circumstances we can apply the so-called rapid ethnography. The image obtained in this way can answer some questions for us, and although we do not get a full overview of social relations, the answers obtained in this way can be useful. We can afford to proceed in this way, for example, in environments that are already quite well researched overall, given that we are interested in very specific questions.
Thus, we often encounter rapid ethnography in applied research, for example in evaluating the benefits of some government measures or projects led by non-governmental organizations. Therefore, rapid ethnography can help us determine whether the project achieved the intended goals, what obstacles arose, or whether it did not have any serious (and therefore relatively quickly observable) consequences which were not anticipated.
