Customize automatically generated TOC on jekyll

[meera1002]

In _config.yml I have the following setting that ensures that only h2 elements show up in the automatically generated table of contents.
toc:
min_level: 2 # default: 1
max_level: 2 # default: 6
This works fine, but on some pages, I would like to include h3 elements in the toc as well. So I want to change the max_level to 3 in a particular case. Is this possible? I want to change max_level value dynamically from the template code. Please help
