Can call window.scrollTo() in Selenium.
To take a random page as example,so can try to figure out how much to scroll(i take a guess on 800 here) before taking new screenshot.
Turn of --headless as i use here can also help to see what's going on.

from selenium import webdriver
from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument("--headless")
options.add_argument("window-size=1920,1080")
browser = webdriver.Chrome(executable_path=r'C:\cmder\bin\chromedriver.exe', options=options)
browser.get('https://www.tesmanian.com/blogs/tesmanian-blog')
browser.save_screenshot("page1.png")
browser.execute_script("window.scrollTo(0, 800);")
browser.save_screenshot("page2.png")
browser.close()

I try do it

from selenium import webdriver # $ pip install selenium
from selenium.webdriver.chrome.options import Options
DRIVER = 'C:\selenium\chromedriver.exe'
driver = webdriver.Chrome(DRIVER)

options = webdriver.ChromeOptions()
options.add_argument('headless')
options.add_argument(f'window-size={1920},{1080}')
options.add_argument('hide-scrollbars')

# get chromedriver fro
# https://sites.google.com/a/chromium.org/.../downloads
browser = webdriver.Chrome(chrome_options=options)
browser.get('stackoverflow.com')
browser.save_screenshot('filename.png')

but I have an error

Use code tags
Do not use \ in file path on Windows because of escape character ,see that i use r r'path'
Use my code and not the older stuff that you use,then is like this.

from selenium.webdriver.chrome.options import Options

options = Options()
options.add_argument('--headless')

This mean that chromedriver.exe most be in Environment Variables Path.
So i have have added this myself to Path C:\cmder\bin\chromedriver.exe.
Just copy all of my code and make or use a Path that's in Environment Variables Path.

Or this also work,copy code and remove path:

from selenium import webdriver
from selenium.webdriver.chrome.options import Options
import time

options = Options()
#options.add_argument("--headless")
#options.add_argument("window-size=1920,1080")
browser = webdriver.Chrome(executable_path=r'chromedriver.exe', options=options)
browser.get('https://www.tesmanian.com/blogs/tesmanian-blog')
browser.save_screenshot("page1.png")
time.sleep(5)
browser.execute_script("window.scrollTo(0, 800);")
browser.save_screenshot("page2.png")
time.sleep(5)
browser.close()

Now have files in same folder,eg make a folder my_sel.
Here also comment out --headless and add som time sleep then it easier to see how window.scrollTo() work.

C:\my_sel\
  |-- sel_screenshot.py
  |-- chromedriver.exe
