You don’t have to do all the lesson at once, as in “all in one batch”.
I make sure to do the radicals first, so I can unlock the new kanji faster. I tend to do 20 lessons in the morning with a mix of vocab and new kanji. I do more lessons in the evening at around 6 so I have time to review them 4 hours later at 10 pm. Repeat for the next days until I’m out of lessons. Sometimes I do more lessons, or do many batches throughout one day.
You can try varying the amount of lessons per batch to find out what works for you. I also recommend reading chapter 4 - 6 of this Ultimate Guide™ if you haven’t already There’s a lot of useful stuff in there
