Change ttl for Hotspot Use

This is probably a foolish question from a Linux noob but I’m trying to install Bazzite online installer from a throttled hotspot and was wondering is there a way I can change the ttl value to 65?

# TTL for local traffic
sudo sysctl net.ipv4.ip_default_ttl=65

# TTL for transit traffic
sudo nft -f - << EOI
add table ip custom
flush table ip custom
add chain ip custom postrouting \
{ type filter hook postrouting priority mangle; }
add rule ip custom postrouting ip ttl set 65

TTL does not effect bandwidth usually.
It is used to stop a packet from being routed forever.
