How to limit swap usage without using sysctl or resizing the partition?

There is the following scenario: I have an HDD disk that uses LVM and I cannot resize the partitions in it, in this disk, there is a swap partition that is 10gb. I also use zram apart from disk based swap, so I cannot tweak sysctl parameters because I am using these values to make zram work well. Also, the swap disk has -1 priority while the zram is top priority, nevertheless, the swap disk usage is way higher than it should be, so I thought resizing it to 1gb would avoid this. The only option that I thought about was setting up fstab to pretend the swap is smaller than it is, but as I researched, could not found a way to configure it. The information about the disk is the following:
