The general answer is No. This depends a lot of the underlying driver (the 
format must allow sequential reading), and how you use it afterwards.

A particular case where this might work is a VRT referencing CSV:/vsistdin/ 
and using that vrt as the source for ogr2ogr

For example with test.vrt being:

<OGRVRTDataSource>
  <OGRVRTLayer name="test">
    <SrcDataSource>CSV:/vsistdin/</SrcDataSource>
    <SrcLayer>layer</SrcLayer>
  </OGRVRTLayer>
</OGRVRTDataSource>

you can do:

cat test.csv | ogr2ogr -f GML out.gml test.vrt
