from fune2fs man page:

-o [^]mount-option[,...]

Set or clear the indicated default mount options in the filesystem. Default mount options can be overridden by mount options specified either in /etc/fstab(5) or on the command line arguments to mount(8). Older kernels may not support this feature; in particular, kernels which predate 2.4.20 will almost certainly ignore the default mount options field in the superblock.

More than one mount option can be cleared or set by separating

features with commas. Mount options prefixed with a caret character ('^') will be cleared in the filesystem's superblock; mount options without a prefix character or prefixed with a plus character ('+') will be added to the filesystem.

The following mount options can be set or cleared using

tune2fs:
