There certainly isn't a configuration parameter to say "make PG dump
faster."

- It is possible that it is taking longer to backup the database because
the database has grown in size. If you have a lot more data captured, this
would be a natural consequence, that you need simply to accept.

But there are additional possibilities...

- Perhaps the database is bloated because an update pattern is leading to a
lot of dead data being left behind. In that case some tables need to be
vacuumed much more often and you should look into the auto vacuum
configuration.

- Perhaps the database has some table that contains a lot of obsolete
data. This would depend heavily on the nature of your application.

You should look to see what data you are collecting that is not of ongoing
value. That may represent data that you should trim out of the database.
That should improve the amount of time it takes to do a backup of the
database.
