Head coach Wayne Pivac concedes Wales may still be unable to play at the Principality Stadium when they return to action.
The stadium in Cardiff is currently a field hospital, which was opened on April 20 to meet the increased demand for beds during the coronavirus pandemic.
Wales remain on lockdown after rugby was halted in March with one full round of the Six Nations to play.
Voting is currently open, but closes on Thursday, and the WRU revealed their three votes would go to Beaumont ahead of rival Agustin Pichot.
Pivac added: “We have got a great opportunity to look at the global season.
“It has been a very difficult question to answer. The game might look a little different, certainly in the short term.
“The global season is one we would all like to see come under scrutiny and come up with something which is suitable for northern and south hemisphere rugby.”
