I hear same question most of the days that I see patients. It is really hard to move one tooth and not move the rest. The exception is when my patients had treatment and one tooth rotates a tiny bit and me move it back but they already been in orthodontic care before.
Orthodontic appliances come with to main flavors: fixed and removable. Clear aligner aka Invisalign is often a good choice for holding every thing and move one tooth but based on your photo it would be hard to move one tooth since we need to create space for that tooth.
Here are some resources that you can read to learn more options for you. Be aware of box orthodontics since there is a consumer alert on that from the American Association of Orthodontists.
Google porth.io and check my clinic webpage we have lots of usefull information that can help you.
