在 AWS 服务器上授予 net_privaddr 权限

Question

在 AWS 服务器上，我需要向用户授予“net_privaddr”权限。我尝试使用以下命令：

/usr/sbin/usermod -K defaultpriv=basic,net_privaddr USER

但在 AWS 服务器上，K 选项不存在。请看：

[root@xxxx dddd]# /usr/sbin/usermod -K defaultpriv=basic,net_privaddr USER
/usr/sbin/usermod: invalid option -- 'K'
Usage: usermod [options] LOGIN

Options:
  -c, --comment COMMENT         new value of the GECOS field
  -d, --home HOME_DIR           new home directory for the user account
  -e, --expiredate EXPIRE_DATE  set account expiration date to EXPIRE_DATE
  -f, --inactive INACTIVE       set password inactive after expiration
                                to INACTIVE
  -g, --gid GROUP               force use GROUP as new primary group
  -G, --groups GROUPS           new list of supplementary GROUPS
  -a, --append                  append the user to the supplemental GROUPS
                                mentioned by the -G option without removing
                                him/her from other groups
  -h, --help                    display this help message and exit
  -l, --login NEW_LOGIN         new value of the login name
  -L, --lock                    lock the user account
  -m, --move-home               move contents of the home directory to the
                                new location (use only with -d)
  -o, --non-unique              allow using duplicate (non-unique) UID
  -p, --password PASSWORD       use encrypted password for the new password
  -s, --shell SHELL             new login shell for the user account
  -u, --uid UID                 new UID for the user account
  -U, --unlock                  unlock the user account
  -Z, --selinux-user            new SELinux user mapping for the user account

[root@xxxx dddd]#

那么，当 Usermod 没有“K”选项时，我该如何授予该权限？

短暂性脑缺血发作，
