I installed Ubuntu 20.04 on my SSD alongside Windows 10, but I can't boot Ubuntu 20.04. It always boots Windows. I ran Boot-Repair, but it didn't work. http://paste.ubuntu.com/p/WvMfFgJvXN/ Here is my Boot Repair Summary.

SFS detected. You may want to retry after converting Windows dynamic partitioning (SFS partitions) to a basic disk. This can be performed via tools such as TestDisk or EASEUS-Partition-Master / MiniTool-Partition-Wizard.
Are you sure you want to continue anyway? yes
Recommended repair: ____________________________________________________________
The default repair of the Boot-Repair utility will reinstall the grub-efi-amd64-signed of
nvme0n1p4,
using the following options: nvme0n1p1/boot/efi,
Additional repair will be performed: unhide-bootmenu-10s win-legacy-basic-fix use-standard-efi-file
/boot/efi added in nvme0n1p4/fstab
Quantity of real Windows: 2
Mount nvme0n1p1 on /mnt/boot-sav/nvme0n1p4/boot/efi

Unhide GRUB boot menu in nvme0n1p4/boot/grub/grub.cfg
An error occurred during the repair.
You can now reboot your computer.
Please do not forget to make your UEFI firmware boot on the Ubuntu 20.04.1 LTS entry (nvme0n1p1/EFI/ubuntu/shimx64.efi file) !
If your computer reboots directly into Windows, try to change the boot order in your UEFI firmware.
If your UEFI firmware does not allow to change the boot order, change the default boot entry of the Windows bootloader.
For example you can boot into Windows, then type the following command in an admin command prompt:
bcdedit /set {bootmgr} path \EFI\ubuntu\shimx64.efi
