10-11 hours of sleep is on the light end for a 2-ish year old, but it's not that extreme; the National Sleep Foundation recommends 11-14 hours at 2 and 10-13 hours at 3, which is echoed by the American Academy of Pediatricians as well. So you're either just below or at the minimum, not far outside of the range by any means. If the child is waking up on their own, and not appearing drowsy during the day (it sounds like that's a definite no!), you're probably doing okay on actual sleep.
Do check in with your pediatrician about sleep every visit, though; we're also a family of shorter sleepers, and I probably could've written this exact question (minus COVID!) when my children were around that age. My 7 and 9 year old children get about 8 hours of sleep now, maybe 9 on the outside, and that seems to be okay for them - but we always talk about it at our pediatrician visits. They can give you tips for recognizing when your child isn't sleeping enough, as well as tips for helping you get more sleep.
Getting to sleep should, by 27 months, be something they can do by themselves, for most children. There are a few things you can do to help this along. One is, unfortunately, cutting out the nap - many children by this age don't need naps anymore, and naps can make night-time sleep harder to begin (as they're just not tired). Changing from 9pm-6am and 1pm-3pm sleep, to 7pm-6am sleep, is appropriate for some children; it was for mine, neither was napping by 2.5 years old. That doesn't necessarily help you in the long run, as you need that nap time to work I'm guessing! But keep it in mind.
As far as during the day: unfortunately, at 2, most children do need a lot of parental involvement. Unless you hand him a screen, which is definitely not an ideal solution, he's going to want to talk to you and play with you. Many of the parents I know who have children in this age range simply split their worktime right now; one parent works 9am-11am, 1pm-3pm, while one works 11am-1pm and 3pm-5pm, something like that (and longer hours if needed - maybe 7am-9am and 5pm-7pm shifts added, for example, to bring you to full time). It's hard to get both of you to 8 hours that way, but it's just how it is for a lot of people right now.
If you have a grandparent or other person who's not working and is available, you could consider having an hour or so of "zoom play", where he interacts with that person over a screen (Zoom, Facetime, Skype, whatever). Some kids can do that for extended periods; I'm not sure how feasible it is at 2, but it might be worth a try at least - every kid is different after all. If it gets you an hour here or there where both of you can work, so much the better.
Make sure you're getting outside with him as often as possible - obviously in a socially distanced, and legal, way - and getting a ton of exercise. It's not only important for his development, but it will help with sleep. When my children are indoors all day, nighttime is harder; when they're running about, it's easier. One thing I have done that worked really well was to go out front, and simply run up and down the block on the sidewalk, shortly before bedtime (say, if bedtime is 9, then at 7). Play races, chasing imaginary friends or animals, that sort of thing, can really help.
