Can you reach level 10 star rank in Pokemon legends arceus before going to Crimson Mirelands?!!

I attempt to reach level 10 star rank in Pokemon legends arceuse before going to Crimson Mirelands but could not because all the remaining research tasks can’t make reach 50000 research points which I discovered lately. how did i attempt the challenge: 2- started doing all the research tasks available to reach the level 9 star rank. 1- I finished all the quest in the Obsidian Fieldlands until the Crimson Mirelands opened just to make sure every things that will be available will be available in the Obsidian Fieldlands like time space distortion. 3- I calculated the remaining research point that i can get if I completed the remaining research tasks available. I discovered that I can not reach level 10 star rank with the remaining research tasks.
