Russia has been under sanctions for years, and even if the US and its vassals impose some new ones, after so long it will not mean much to Russia. If we look at who are the most important trade partners, then we see that China is dominant (imports & exports), while significant places are occupied by the Netherlands, Germany and Belarus (data for 2017). The US may influence Germany or the Netherlands in their decisions, but China, as its most important trading partner, has never and will not support any sanctions against Russia.
This is an option that is on the table and has already been announced by Russia in light of recent events. So even though it would have been expected earlier that all those countries to which the US is constantly imposing sanctions and creating problems will reject US $, it does not seem that this is something they want to do so easily. The US has too much influence in the world, and as much as someone dislikes them it’s hard to get out of their grip.
I remembered one piece of news from 2019 -> Russia's Rosneft to switch to euros in oil products tenders - traders
