You do not need to uninstall the timeshift auto-snap package if you wish to temporarily disable it. It can be very easily disabled through its configuration file. Reading the packages documentation usually answers these kinds of questions.
Perhaps if you'd read the threads on disabling btrfs quotas more closely you would have noticed the info that timeshift will re-enable quotas automatically unless you change that timeshift setting. This can be done within the timeshift GUI or in its configuration file
This stuff has been covered quite extensively on the forum in the past, search is your friend.
