Elementary education degree programs typically include field work (where the student does teaching under supervision) and lab work so they cannot be completely online/distance (unless you assume that elementary education in the foreseeable future will be all online/distance).
However, some courses may be suitable to be done in online/distance format, given motivated students and instructors who can do that format well.
Obviously, the concern about COVID-19 has caused many colleges to move many courses to online/distance format, although not necessarily permanently if medical advances eventually reduce the threat that the virus poses.
