How to decrypt EFS files on exFAT USB drive?

I encrypted one of folders on my exFAT USB Drive without knowing EFS specifics. Then I reinstalled Windows 11 (same user and password) on it and discovered that I cannot open some files in that encrypted folder. Simply unchecking Encrypted attribute from files gives unknown error. Googling lead me to Elcomsoft Advanced EFS Password Recovery app. I guess it could help me if my drive was NTFS formatted. Using some standard Windows utility which popped up as a reminder to back up my certificates I managed to get .pfx file from the main NTFS drive. Please suggest next steps to decrypt/open encrypt
