It is possible only after functionalization of GO by some suitable organic group or polymer which could make GO hydrophobic in nature. There are some references in J Material chemistry. You can follow them

Graphene oxide is strongly hydrophylic and can generate stable and homogeneous colloidal dispersions in aqeous and various POLAR organic solvents due to the electrostatic repulsion between the negatively charged graphene oxide sheets. This charge comes from oxygen-containing functional groups covalently bonded to surface of graphene. Hexane is nonpolar solvent. Therefore, it can not be used for preparation of stable dispersion.
"The support was then rinsed with Isopar to remove excessive TMC and
subsequently soaked in GO solution (2.8 wt.%, dissolved in Isopar), which had been sonicated to break up any GO aggregates possibly formed due to their high hydrophilicity, for 15 min to attach the first layer of GO nanosheets onto the membrane support."
Quoted from the method section of the Meng and Baoxia paper "Enabling Graphene Oxide Nanosheets as Water Separation Membranes."
Sounds like they needed plenty of sonication. Not sure it would be a stable GO solution/colloid in such a non-polar solvent. Could be more an particle suspension from the few times I have worked with one particular GO sample in polar and non-polar solvents. (GO usually dissolves in polar solvents, but instead probably can be temporarily suspended as fine particles in non-polar solvents)
The other consideration with GO is that the amount of polar functional groups is a variable. Different graphite-to-GO methods can add different amounts of polar functional groups which could influence the solubility. Also some of the GO's polar functional groups can be easily removed with heating and exposure to light, so a GO sample may become more non-polar with time, storage, or processing (depending on the conditions).
I think it might be possible but after functionalization of Graphene oxide by a suitable organic group or polymer which could make Graphene oxide hydrophobic .
The modification/grafting of GO with long chain alkylamines is in principle required to render GO hydrophobic and compatible with organic media, such as styrene. One pratical example can be found here: (Wang G., "Synthesis of enhanced hydrophilic and hydrophobic graphene oxide nanosheets by a solvothermal method", Carbon 47, 2009, 68–72;). In the paper hydrophobic GO was prepared via the functionalization with phenylisocynate (C6H5NCO).
