Tested deploying an agent with memory:

const agent = new bedrock.Agent(this, 'Agent', {
      foundationModel: bedrock.BedrockFoundationModel.ANTHROPIC_CLAUDE_3_5_SONNET_V1_0,
      instruction: 'You are a helpful and friendly agent that answers questions about literature.',
      memory: bedrock.Memory.sessionSummary({
        maxRecentSessions: 10,
        memoryDurationDays: 20,
      }),
      userInputEnabled: true,
      shouldPrepareAgent:true
    });

When not specifying memory, it is disabled as expected:
