Trying to run wireguard script wg-quick which using resolvconf command
Get error /opt/bin/wg-quick: line 31: resolvconf: command not found
Which entware package need to be installed for this resolvconf command?

I suggest you follow the guide on this page to setup your wireguard....

I have RT-AC68U which mentioned in this forum not stable for wireguard
However I found website link below and I'm trying now but get stuck with this unsupported resolvconf command

WireGuard on ASUS WiFi router with Broadcom ARMv7 32-bit chipset running ASUSWRT-Merlin — nixFAQ

Often BusyBox has stripped down versions of software. If you have entware installed, you can use

Opkg list

To see if there are any full versions available for resolvconf. Pipe the output to grep to help your search

(On a tiny keyboard, so I can't type this I want it).

I believe the following is from a back-level version of wg-quick....

set_dns() {
    [[ ${#DNS[@]} -gt 0 ]] || return 0
    # TODO: this is a horrible way of doing it. Has OpenBSD no resolvconf?
    cmd cp /etc/resolv.conf "/etc/resolv.conf.wg-quick-backup.$INTERFACE"
    cmd printf 'nameserver %s\n' "${DNS[@]}" > /etc/resolv.conf
}

unset_dns() {
    [[ -f "/etc/resolv.conf.wg-quick-backup.$INTERFACE" ]] || return 0
    cmd mv "/etc/resolv.conf.wg-quick-backup.$INTERFACE" /etc/resolv.conf
}

so if the Wireguard DNS directive is configured (you can try commenting it out) then the contents of '/etc/resolv.conf' is overwritten after the backup is created.

Thanks for this script modification
However now the script stuck at
sysctl: command not found
I check opkg also doesn't have sysctl
Any suggestion how to change the script, not to use sysctl command?
