[tor-relays] Using unattended upgrades with tor expert bundle

Hi all, So I have been running an OBFS4 bridge via the Tor Expert Bundle for a year now, and it is going quite well. However, from what I have researched, using unattended upgrades to keep tor up to date is configured in the torrc file. I am wondering, can this be configured in tor expert bundle? Thanks very much. --Keifer
