trying to play together pc and ps5

first i logged in with my same EA account on pc and ps5 cause i thought my pc UT progress will transfer to ps5 but it was not possible. so my brother played on ps5 made his own UT but now we figured that cause the account is same we cant even play at the same time nor we can play vs each other cause the account is same, I am asking if there is any way i can unlink the ps5 account from my profile and his UT progress will be transferred to the different EA account that he will make to link the ps5 with it? i really need help in this one i dont wanna break his heart by deleting his progress, he is so attached but i also dont wanna delete mine. Can anyone please help?
