Aside from semantics, National Bolshevism isn't that different from other Third Positionist ideologies like Baathism, Strasserism, and whatever North Korea's system is.
A strong state and/or dictator with a cult of personality, nationalist/anti-imperialist and socialist rhetoric, and either a planned economy or heavy-handed state intervention describes Saddam Hussein, the Assads, Ceausescu's Romania, and Zimbabwe under Mugabe pretty well.
National Bolshevism has a heavy dose of Stalin apologism and Soviet nostalgia, so a self-described National Bolshevik Regime seems unlikely outside the former Soviet Union. The actual National Bolshevik regime splinter over whether they should support Putin or not.
Since the 2000s, Russia's economic recovery and the resurgence of Orthodox Christianity have substantially reduced any potential support for the bizarre chimera of Nazism and Stalinism that is nazbol. The ideology only seems to be an obscure meme outside of the Russian federation.
