Documentation at https://doc.dovecot.org/configuration_manual/mail_location/
provides solution(s) for you:
SUBSCRIPTIONS
Specifies the filename used for storing subscriptions. The default is
subscriptions. If you?re trying to avoid name collisions with a mailbox named
subscriptions, then also consider setting MAILBOXDIR.
MAILBOXDIR
Specifies directory name under which all mailbox directories are stored. The
default is empty unless otherwise described in the mailbox format pages.
Would either one be something you can consider? If you set MAILBOXDIR=mbox then
your mailboxes go into ~/Maildir/mbox/
