@Anchal gupta , Based on my research, there are far fewer cases left in modern enterprises where SMB1 is the only option. Some legit reasons:
- You’re still running XP or WS2003 under a custom support agreement.
- You have old management software that demands admins browse via the so-called ‘network' aka 'network neighborhood’ master browser list.
- You run old multi-function printers with old firmware in order to “scan to share”.

For SCOM, after researching, I didn't find any article mention the impact.
To double confirm, we can capture network trace on SCOM server or enable auditing mentioned in the following link: to check
