man tune2fs
[...]
-c max-mount-counts
Adjust the number of mounts after which the filesystem will be checked by e2fsck(8). If max-mount-counts is 0 or -1, the number of
times the filesystem is mounted will be disregarded by e2fsck(8) and the kernel.
[...]
-i interval-between-checks[d|m|w]
Adjust the maximal time between two filesystem checks. No suffix or d will interpret the number interval-between-checks as days, m as
months, and w as weeks. A value of zero will disable the time-dependent checking.--
