Running apache on ubuntu-20, using chruby with ruby 2.6.6 and 3.0.4 installed. At present, the site starts phusion passenger as follows in the site.conf file:
LoadModule passenger_module /opt/rubies/ruby-3.0.4/lib/ruby/gems/3.0.0/gems/passenger-6.0.14/buildout/apache2/mod_passenger.so
<IfModule mod_passenger.c>
PassengerRoot /opt/rubies/ruby-3.0.4/lib/ruby/gems/3.0.0/gems/passenger-6.0.14/
PassengerDefaultRuby /opt/rubies/ruby-3.0.4/bin/ruby
</IfModule>
I have an additional version of redmine I wish to run under ruby 2.6.6. In the user account for that redmine, I have a .ruby-version which specifies 2.6.6. When visiting the home page, I get a passenger error:

I'm guessing I need to run a separate passenger under ruby 2.6.6 if I want the redmine app itself to run under 2.6.6. Is this correct? If so, can I specify two passengers running from two different ruby versions on the same site? Or do I need a separate site for each one?
Or should passenger, running under ruby 3.0.4, be able to load a redmine running under 2.6.6?
