As Beau said, more information is needed including maybe the text of this letter, the recall number, and of course your specific RV information.
EDIT: A little Internet research found this information:
Thor Motor Coach (TMC) is recalling certain 2017-2021 Freedom Elite motorhomes. A 100amp converter breaker was incorrectly installed at the battery tray when a 70amp breaker is required, possibly resulting in the wiring connected to the breaker overheating.
TMC will notify owners, and dealers will replace the converter breaker with one of the correct amperage if needed, free of charge. The recall is expected to begin September 22, 2020. Owners may contact TMC customer service at 1-855-2867. TMC’s number for this recall is RC000199.
DC breakers are located in the battery compartment or for Class C MHs with house batteries under the steps, very close to the battery location.
So the answer to the OP's question is "Yes, you can do it".
