Olá estou tentando mudar algumas permissoes em /proc/sys/net/ipv4/

/proc/sys/net/ipv4/tcp_fin_timeout: Operation not permitted
/proc/sys/net/ipv4/tcp_keepalive_time: Operation not permitted
/proc/sys/net/ipv4/tcp_window_scaling: Operation not permitted
/proc/sys/net/ipv4/tcp_sack: Operation not permitted
/proc/sys/net/ipv4/tcp_max_syn_backlog: Operation not permitted
/proc/sys/net/ipv4/tcp_syncookies: Operation not permitted
/proc/sys/net/ipv4/icmp_echo_ignore_broadcasts: Operation not permitted
/proc/sys/net/ipv4/icmp_ignore_bogus_error_responses: Operation not permitted

Já tentei usar chattr -i nos arquivos e me retorna o erro
chattr: Inappropriate ioctl for device while reading flags on XXXXX

sou root e não consigo alterar esses arquivos.
