How to suppress output for set +v / set +o verbose (disabling verbose flag) in bash?

Script

#!/bin/bash -v
echo "verbose echo"
{ set +v; } &>/dev/null
echo "non verbose echo"

gives the following output:

echo "verbose echo"
verbose echo
{ set +v; } &>/dev/null
non verbose echo

I want to suppress output for { set +v; } &>/dev/null and get the following output:

echo "verbose echo"
verbose echo
non verbose echo

I tried the approach above which is described here for suppressing output for disabling xtrace (x) flag with command { set +x; } &>/dev/null and it is working for this xtrace flag. Have not found related info in manuals for bash and set.

As work around this can be achieved by means of subshell call like shown here. But is this possible without using subshell?
