Bowing during Oleinu

What is minhag Ashkenaz re bowing during Oleinu (not in musaf of Rosh Hashonoh or Yom Kippur, but year round) ?

Just to explain about the question. The background to the question was that I recalled seeing somewhere that there is a minhog not to do the bowing of the head and upper body during Oleinu, so I was curious (lo habayshan lomeid) about minhag Ashkenaz in the matter.

I think I now found now where I saw that there was a minhag not to bow - it seems that it is minhag haGR"A (מובא קודם עלינו בּסידור אזור אליהו ע"פּ נוסח הגר"א שיצא לאור בּשנים האחרונות בּא"י, ועי"ש טעמו).

Since at times minhag haGR"A is like minhag Ashkenaz (e.g. re saying nikadeish.....,that only the chazan says it), I was wondering if that might have been the case here as well.

Thanks for the response.
