How to permanently disable filesystem check on boot Ubuntu 20.04 LTS?

So first of all its no a duplicate question, because i tried all options of the same questions and none of it worked.

I tried this one (it didnt work): How do I disable filesystem checking on boot in 20.04?

I tried to edit /etc/fstab as super user and change dump and pass to 0 on my root partition, didn't work as well.

I just did a fresh installation of ubuntu on my SSD and i'm trying to disable it, so i can say all my configs are default.

Also i'm using dual-boot with Windows 10 on the same disk, i don't know if this has someting to do, but may be good let you know.

The only thing that worked (but not permanently) was append fastboot in Ubuntu option when i'm on GRUB screen, after pression e with Ubuntu selected.

Let's manually check your file system...

• boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
• open a terminal window by pressing Ctrl+Alt+T
• type sudo fdisk -l
• identify the /dev/sdXX device name for your "Linux Filesystem"
• type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
• repeat the fsck command if there were errors
• type reboot

Note: If fsck finds/repairs problems, remove fastboot from your /etc/default/grub, and sudo update-grub.

Note: You can also start gparted and see if it finds any problem with the partition table, or errors when the partition is "Checked" (a choice from the menu).

Note: You can also sudo fdisk -l to see if it finds any partition errors.

Note: You can also use the Disks SMART Data & Tests window to determine if there's any pending disk failure. Ignore any "Your disk is OK" messages.

Note: If you dual-boot with Windows, and you have a Windows driver installed that allows you to read/write to Linux ext2/3/4 partitions, remove this driver asap, as it WILL corrupt Linux partitions.
